According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Use-after-free vulnerability in fs/block_dev.c in the     Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging     improper access to a certain error     field.(CVE-2020-15436)

  - An out-of-bounds memory write flaw was found in how the     Linux kernel's Voice Over IP H.323 connection tracking     functionality handled connections on ipv6 port 1720.
    This flaw allows an unauthenticated remote user to     crash the system, causing a denial of service. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-14305)

  - Improper input validation in BlueZ may allow an     unauthenticated user to potentially enable escalation     of privilege via adjacent access.(CVE-2020-12351)

  - In the Linux kernel 4.14 longterm through 4.14.165 and     4.19 longterm through 4.19.96 (and 5.x before 5.2),     there is a use-after-free (write) in the     i915_ppgtt_close function in     drivers/gpu/drm/i915/i915_gem_gtt.c, aka     CID-7dc40713618c. This is related to     i915_gem_context_destroy_ioctl in     drivers/gpu/drm/i915/i915_gem_context.c.(CVE-2020-7053)

  - In kbd_keycode of keyboard.c, there is a possible out     of bounds write due to a missing bounds check. This     could lead to local escalation of privilege with no     additional execution privileges needed. User     interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-144161459(CVE-2020-0431)

  - In various methods of hid-multitouch.c, there is a     possible out of bounds write due to a missing bounds     check. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-162844689References: Upstream kernel(CVE-2020-0465)

  - mwifiex_cmd_802_11_ad_hoc_start in     drivers/net/wireless/marvell/mwifiex/join.c in the     Linux kernel through 5.10.4 might allow remote     attackers to execute arbitrary code via a long SSID     value, aka CID-5c455c5ab332.(CVE-2020-36158)

  - A flaw was found in the way RTAS handled memory     accesses in userspace to kernel communication. On a     locked down (usually due to Secure Boot) guest system     running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to     further increase their privileges to that of a running     kernel.(CVE-2020-27777)

  - An issue was discovered in romfs_dev_read in     fs/romfs/storage.c in the Linux kernel before 5.8.4.
    Uninitialized memory leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)

  - An issue was discovered in kmem_cache_alloc_bulk in     mm/slub.c in the Linux kernel before 5.5.11. The     slowpath lacks the required TID increment, aka     CID-fd4d9c7d0c71.(CVE-2020-29370)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c.(CVE-2020-8648)

  - A buffer over-read (at the framebuffer layer) in the     fbcon code in the Linux kernel before 5.8.15 could be     used by local attackers to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs     filesystem image, performing some operations, and then     making a syncfs system call can lead to a     use-after-free in __mutex_lock in     kernel/locking/mutex.c. This is related to     mutex_can_spin_on_owner in kernel/locking/mutex.c,
    __btrfs_qgroup_free_meta in fs/btrfs/qgroup.c, and     btrfs_insert_delayed_items in     fs/btrfs/delayed-inode.c.(CVE-2019-19813)

  - gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c     in the rpcsec_gss_krb5 implementation in the Linux     kernel through 5.6.10 lacks certain domain_release     calls, leading to a memory leak.(CVE-2020-12656)

  - A flaw was found in the Linux kernels implementation of     MIDI, where an attacker with a local account and the     permissions to issue an ioctl commands to midi devices,     could trigger a use-after-free. A write to this     specific memory while freed and before use could cause     the flow of execution to change and possibly allow for     memory corruption or privilege     escalation.(CVE-2020-27786)

  - A flaw memory leak in the Linux kernel performance     monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this     flaw to starve the resources causing denial of     service.(CVE-2020-25704)

  - A flaw was found in the Linux Kernel before 5.8-rc6 in     the ZRAM kernel module, where a user with a local     account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - A vulnerability was found in the Linux Kernel where the     function sunkbd_reinit having been scheduled by     sunkbd_interrupt before sunkbd being freed. Though the     dangling pointer is set to NULL in sunkbd_disconnect,     there is still an alias in sunkbd_reinit causing Use     After Free.(CVE-2020-25669)

  - A flaw was found in the Linux kernel. A use-after-free     was found in the way the console subsystem was using     ioctls KDGKBSENT and KDSKBSENT. A local user could use     this flaw to get read memory access out of bounds. The     highest threat from this vulnerability is to data     confidentiality.(CVE-2020-25656)

  - The Linux kernel before version 5.8 is vulnerable to a     NULL pointer dereference in     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init
    _ports() that allows local users to cause a denial of     service by using the p->serial_in pointer which     uninitialized.(CVE-2020-15437)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - A stack information leak flaw was found in s390/s390x     in the Linux kernel's memory manager functionality,     where it incorrectly writes to the     /proc/sys/vm/cmm_timeout file. This flaw allows a local     user to see the kernel data.(CVE-2020-10773)

  - ** DISPUTED ** drivers/gpu/drm/radeon/radeon_display.c     in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer     dereference. NOTE: A third-party software maintainer     states that the work queue allocation is happening     during device initialization, which for a graphics card     occurs during boot. It is not attacker controllable and     OOM at that time is highly unlikely.(CVE-2019-16230)

  - A flaw was found in the Linux Kernel in versions after     4.5-rc1 in the way mremap handled DAX Huge Pages. This     flaw allows a local attacker with access to a DAX     enabled storage to escalate their privileges on the     system.(CVE-2020-10757)

  - A pivot_root race condition in fs/namespace.c in the     Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before     4.19.119, and 5.x before 5.3 allows local users to     cause a denial of service (panic) by corrupting a     mountpoint reference counter.(CVE-2020-12114)

  - A slab-out-of-bounds read in fbcon in the Linux kernel     before 5.9.7 could be used by local attackers to read     privileged information or potentially crash the kernel,     aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for     manipulations such as font height.(CVE-2020-28974)

  - Insufficient control flow in certain data structures     for some Intel(R) Processors with Intel(R) Processor     Graphics may allow an unauthenticated user to     potentially enable information disclosure via local     access.(CVE-2019-14615)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs     filesystem image, performing some operations, and     unmounting can lead to a use-after-free in     btrfs_queue_work in     fs/btrfs/async-thread.c.(CVE-2019-19377)

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-147802478References: Upstream kernel(CVE-2020-0466)

  - ** DISPUTED ** fs/nfsd/nfs3xdr.c in the Linux kernel     through 5.10.8, when there is an NFS export of a     subdirectory of a filesystem, allows remote attackers     to traverse to other parts of the filesystem via     READDIRPLUS. NOTE: some parties argue that such a     subdirectory export is not intended to prevent this     attack see also the exports(5) no_subtree_check default     behavior.(CVE-2021-3178)

  - A flaw was found in the Linux kernels eBPF     implementation. By default, accessing the eBPF verifier     is only accessible to privileged users with     CAP_SYS_ADMIN. A local user with the ability to insert     eBPF instructions can abuse a flaw in eBPF to corrupt     memory. The highest threat from this vulnerability is     to confidentiality, integrity, as well as system     availability.(CVE-2021-29154)

  - A flaw memory leak in the Linux kernel webcam device     functionality was found in the way user calls ioctl     that triggers video_usercopy function. The highest     threat from this vulnerability is to system     availability.(CVE-2021-30002)

  - A flaw was found in the Nosy driver in the Linux     kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free     when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2021-3483)

  - A flaw in the Linux kernels implementation of the RPA     PCI Hotplug driver for power-pc. A user with     permissions to write to the sysfs settings for this     driver can trigger a buffer overflow when writing a new     device name to the driver from userspace, overwriting     data in the kernel's stack.(CVE-2021-28972)

  - A race condition flaw was found in get_old_root in     fs/btrfs/ctree.c in the Linux kernel in btrfs     file-system. This flaw allows a local attacker with a     special user privilege to cause a denial of service due     to not locking an extent buffer before a cloning     operation. The highest threat from this vulnerability     is to system availability.(CVE-2021-28964)

  - A flaw was found in the Linux kernel. The usbip driver     allows attackers to cause a denial of service (GPF)     because the stub-up sequence has race conditions during     an update of the local and shared status. The highest     threat from this vulnerability is to system     availability.(CVE-2021-29265)

  - An out-of-bounds (OOB) memory access flaw was found in     x25_bind in net/x25/af_x25.c in the Linux kernel. A     bounds check failure allows a local attacker with a     user account on the system to gain access to     out-of-bounds memory, leading to a system crash or a     leak of internal kernel information. The highest threat     from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2020-35519)

  - There is a flaw reported in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in     nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The     issue results from the lack of validating the existence     of an object prior to performing operations on the     object. An attacker with a local account with a root     privilege, can leverage this vulnerability to escalate     privileges and execute code in the context of the     kernel.(CVE-2021-20292)

  - A flaw was found in the JFS filesystem code. This flaw     allows a local attacker with the ability to set     extended attributes to panic the system, causing memory     corruption or escalating privileges. The highest threat     from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2020-27815)

  - A flaw was found in the Linux kernel. A denial of     service problem is identified if an extent tree is     corrupted in a crafted ext4 filesystem in     fs/ext4/extents.c in ext4_es_cache_extent.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):In uvc_scan_chain_forward     of uvc_driver.c, there is a possible linked list     corruption due to an unusual root cause. This could     lead to local escalation of privilege in the kernel     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:

    A-111893654References: Upstream kernel.(CVE-2020-0404)A     flaw was found in the Linux kernel in versions from     2.2.3 through 5.9.rc5. When changing screen size, an     out-of-bounds memory write can occur leading to memory     corruption or a denial of service. This highest threat     from this vulnerability is to system     availability.(CVE-2020-14390)A TOCTOU mismatch in the     NFS client code in the Linux kernel before 5.8.3 could     be used by local attackers to corrupt memory or     possibly have unspecified other impact because a size     check is in fs4proc.c instead of fsfs4xdr.c, aka     CID-b4487b935452.(CVE-2020-25212)A flaw was found in     the Linux kernel before 5.9-rc4. A failure of the file     system metadata validator in XFS can cause an inode     with a valid, user-creatable extended attribute to be     flagged as corrupt. This can lead to the filesystem     being shutdown, or otherwise rendered inaccessible     until it is remounted, leading to a denial of service.
    The highest threat from this vulnerability is to system     availability.(CVE-2020-14385)In the Linux kernel before     5.7.8, fsfsd/vfs.c (in the NFS server) can set     incorrect permissions on new filesystem objects when     the filesystem lacks ACL support, aka CID-22cf8419f131.
    This occurs because the current umask is not     considered.(CVE-2020-24394)The rbd block device driver     in drivers/block/rbd.c in the Linux kernel through     5.8.9 used incomplete permission checking for access to     rbd devices, which could be leveraged by local     attackers to map or unmap rbd block devices, aka     CID-f44d04e696fe.(CVE-2020-25284)An issue was     discovered in net/ipv4/sysctl_net_ipv4.c in the Linux     kernel before 5.0.11. There is a net/ipv4/tcp_input.c     signed integer overflow in tcp_ack_update_rtt() when     userspace writes a very large integer to /proc/sys     et/ipv4/tcp_min_rtt_wlen, leading to a denial of     service or possibly unspecified other impact, aka     CID-19fad20d15a6.(CVE-2019-18805)Insufficient input     validation in i40e driver for Intel(R) Ethernet 700     Series Controllers versions before 7.0 may allow an     authenticated user to potentially enable a denial of     service via local access.(CVE-2019-0147)Buffer overflow     in i40e driver for Intel(R) Ethernet 700 Series     Controllers versions before 7.0 may allow an     authenticated user to potentially enable an escalation     of privilege via local access.(CVE-2020-0145)A race     condition between hugetlb sysctl handlers in     mm/hugetlb.c in the Linux kernel before 5.8.8 could be     used by local attackers to corrupt memory, cause a NULL     pointer dereference, or possibly have unspecified other     impact, aka CID-17743798d812.(CVE-2020-25285)A memory     out-of-bounds read flaw was found in the Linux kernel     before 5.9-rc2 with the ext3/ext4 file system, in the     way it accesses a directory with broken indexing. This     flaw allows a local user to crash the system if the     directory exists. The highest threat from this     vulnerability is to system     availability.(CVE-2020-14314)A missing CAP_NET_RAW     check in NFC socket creation in net fc/rawsock.c in the     Linux kernel before 5.8.2 could be used by local     attackers to create raw sockets, bypassing security     mechanisms, aka CID-26896f01467a.(CVE-2020-26088)A flaw     was found in the HDLC_PPP module of the Linux kernel in     versions before 5.9-rc7. Memory corruption and a read     overflow is caused by improper input validation in the     ppp_cp_parse_cr function which can cause the system to     crash or cause a denial of service. The highest threat     from this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-25643)The Linux kernel, as used     in Red Hat Enterprise Linux 7, kernel-rt, and     Enterprise MRG 2 and when booted with UEFI Secure Boot     enabled, allows local users to bypass intended     securelevel/secureboot restrictions by leveraging     improper handling of secure_boot flag across kexec     reboot.(CVE-2015-7837)A flaw was found in the Linux     kernel's implementation of biovecs in versions before     5.9-rc7. A zero-length biovec request issued by the     block subsystem could cause the kernel to enter an     infinite loop, causing a denial of service. This flaw     allows a local attacker with basic privileges to issue     requests to a block device, resulting in a denial of     service. The highest threat from this vulnerability is     to system availability.(CVE-2020-25641)A flaw was found     in the Linux kernel before 5.9-rc4. Memory corruption     can be exploited to gain root privileges from     unprivileged processes. The highest threat from this     vulnerability is to data confidentiality and     integrity.(CVE-2020-14386)A flaw was found in the Linux     kernel in versions before 5.9-rc7. Traffic between two     Geneve endpoints may be unencrypted when IPsec is     configured to encrypt traffic for the specific UDP port     used by the GENEVE tunnel allowing anyone between the     two endpoints to read the traffic unencrypted. The main     threat from this vulnerability is to data     confidentiality.(CVE-2020-25645)perf: Fix race in     perf_mmap_close function.(CVE-2020-14351)An information     leak flaw was found in the way the Linux kernel's     Bluetooth stack implementation handled initialization     of stack memory when handling certain AMP packets. A     remote attacker in adjacent range could use this flaw     to leak small portions of stack memory on the system by     sending a specially crafted AMP packets. The highest     threat from this vulnerability is to data     confidentiality.(CVE-2020-12352)A flaw was found in the     way the Linux kernel Bluetooth implementation handled     L2CAP packets with A2MP CID. A remote attacker in     adjacent range could use this flaw to crash the system     causing denial of service or potentially execute     arbitrary code on the system by sending a specially     crafted L2CAP packet. The highest threat from this     vulnerability is to data confidentiality and integrity     as well as system availability.(CVE-2020-12351)A heap     buffer overflow flaw was found in the way the Linux     kernel's Bluetooth implementation processed extended     advertising report events. This flaw allows a remote     attacker in an adjacent range to crash the system,     causing a denial of service or to potentially execute     arbitrary code on the system by sending a specially     crafted Bluetooth packet. The highest threat from this     vulnerability is to confidentiality, integrity, as well     as system availability.(CVE-2020-24490)** RESERVED **     This candidate has been reserved by an organization or     individual that will use it when announcing a new     security problem. When the candidate has been     publicized, the details for this candidate will be     provided.(CVE-2020-25656)In skb_to_mamac of     networking.c, there is a possible out of bounds write     due to an integer overflow. This could lead to local     escalation of privilege with no additional execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-143560807(CVE-2020-0432)A     slab-out-of-bounds read in fbcon in the Linux kernel     before 5.9.7 could be used by local attackers to read     privileged information or potentially crash the kernel,     aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for     manipulations such as font height.(CVE-2020-28974)A     flaw memory leak in the Linux kernel performance     monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this     flaw to starve the resources causing denial of     service.(CVE-2020-25704)A buffer over-read (at the     framebuffer layer) in the fbcon code in the Linux     kernel before 5.8.15 could be used by local attackers     to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)There is a     use-after-free problem seen due to a race condition     between the release of ptp_clock and cdev while     resource deallocation. When a (high privileged) process     allocates a ptp device file (like /dev/ptpX) and     voluntarily goes to sleep. During this time if the     underlying device is removed, it can cause an     exploitable condition as the process wakes up to     terminate and clean all attached files. The system     crashes due to the cdev structure being invalid (as     already freed) which is pointed to by the     inode.(CVE-2020-10690)A device tracking vulnerability     was found in the flow_dissector feature in the Linux     kernel. This flaw occurs because the auto flowlabel of     the UDP IPv6 packet relies on a 32-bit hashmd value as     a secret, and jhash (instead of siphash) is used. The     hashmd value remains the same starting from boot time     and can be inferred by an     attacker.(CVE-2019-18282)Use-after-free vulnerability     in fs/block_dev.c in the Linux kernel before 5.8 allows     local users to gain privileges or cause a denial of     service by leveraging improper access to a certain     error field.(CVE-2020-15436)The Linux kernel before     version 5.8 is vulnerable to a NULL pointer dereference     in     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init
    _ports() that allows local users to cause a denial of     service by using the p->serial_in pointer which     uninitialized.(CVE-2020-15437)An issue was discovered     in kmem_cache_alloc_bulk in mm/slub.c in the Linux     kernel before 5.5.11. The slowpath lacks the required     TID increment, aka CID-fd4d9c7d0c71.(CVE-2020-29370)An     issue was discovered in the Linux kernel before 5.2.6.
    On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault     statistics are inappropriately freed, aka     CID-16d51a590a8c.(CVE-2019-20934)An issue was     discovered in romfs_dev_read in fs/romfs/storage.c in     the Linux kernel before 5.8.4. Uninitialized memory     leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)An issue was     discovered in the Linux kernel before 5.7.3, related to     mm/gup.c and mm/huge_memory.c. The get_user_pages (aka     gup) implementation, when used for a copy-on-write     page, does not properly consider the semantics of read     operations and therefore can grant unintended write     access, aka CID-17839856fd58.(CVE-2020-29374)A flaw was     found in the way RTAS handled memory accesses in     userspace to kernel communication. On a locked down     (usually due to Secure Boot) guest system running on     top of PowerVM or KVM hypervisors (pseries platform) a     root like local user could use this flaw to further     increase their privileges to that of a running     kernel.(CVE-2020-27777)In kbd_keycode of keyboard.c,     there is a possible out of bounds write due to a     missing bounds check. This could lead to local     escalation of privilege with no additional execution     privileges needed.
