Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the linux package has been released.

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

  - In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. 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-185125206References: Upstream kernel (CVE-2021-39698)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The     RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive     information from kernel memory. (CVE-2022-25375)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has     EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to     obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)

  - In drivers/usb/gadget/udc/udc-xilinx.c in the Linux kernel before 5.16.12, the endpoint index is not     validated and might be manipulated by the host for out-of-array access. (CVE-2022-27223)

  - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and     net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap     objects and may cause a local privilege escalation threat. (CVE-2022-27666)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to     the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be     encountered. In one case, an error encountered earlier might be discarded by later processing, resulting     in the caller assuming successful mapping, and hence subsequent operations trying to access space that     wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery     from the error. This affects drivers/block/xen-blkback/blkback.c. (CVE-2021-26930)

  - The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use     uninitialized or stale values. This initialization went too far and may under certain conditions also     overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking     persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died,     leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable.
    XSA-365 was classified to affect versions back to at least 3.11. (CVE-2021-28688)

  - In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has     a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8. (CVE-2021-28972)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when     transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context.
    This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture.
    (CVE-2021-38300)

  - In gre_handle_offloads of ip_gre.c, there is a possible page fault due to an invalid memory access. This     could lead to local information disclosure with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-150694665References: Upstream kernel (CVE-2021-39633)

  - In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. 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-185125206References: Upstream kernel (CVE-2021-39698)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file. (CVE-2021-45868)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain     privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past     commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the     O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a     regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file     descriptor. (CVE-2022-24448)

  - drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.
    (CVE-2022-24958)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain,which can cause a use-     after-free.This issue needs to handle return with proper preconditions,as it can lead to a kernel     information leak problem caused by a local,unprivileged attacker. (CVE-2022-1016)

  - kernel: Null pointer dereference and use after free in ax25_release() (CVE-2022-1199)

  - A use-after-free flaw was found in the Linux kernel's Amateur Radio AX.25 protocol functionality in the     way a user connects with the protocol. This flaw allows a local user to crash the system. (CVE-2022-1204)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5096 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation,     denial of service or information leaks. CVE-2020-29374 Jann Horn of Google reported a flaw in Linux's     virtual memory management. A parent and child process initially share all their memory, but when either     writes to a shared page, the page is duplicated and unshared (copy-on-write). However, in case an     operation such as vmsplice() required the kernel to take an additional reference to a shared page, and a     copy-on-write occurs during this operation, the kernel might have accessed the wrong process's memory. For     some programs, this could lead to an information leak or data corruption. This issue was already fixed for     most architectures, but not on MIPS and System z. This update corrects that. CVE-2020-36322,     CVE-2021-28950 The syzbot tool found that the FUSE (filesystem-in-user-space) implementation did not     correctly handle a FUSE server returning invalid attributes for a file. A local user permitted to run a     FUSE server could use this to cause a denial of service (crash). The original fix for this introduced a     different potential denial of service (infinite loop in kernel space), which has also been fixed.
    CVE-2021-3640 Lin Ma discovered a race condiiton in the Bluetooth protocol implementation that can lead to     a use-after-free. A local user could exploit this to cause a denial of service (memory corruption or     crash) or possibly for privilege escalation. CVE-2021-3744, CVE-2021-3764 minihanshen reported bugs in the     ccp driver for AMD Cryptographic Coprocessors that could lead to a resource leak. On systems using this     driver, a local user could exploit this to cause a denial of service. CVE-2021-3752 Likang Luo of NSFOCUS     Security Team discovered a flaw in the Bluetooth L2CAP implementation that can lead to a user-after-free.
    A local user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-3760, CVE-2021-4202 Lin Ma discovered race conditions in the NCI (NFC     Controller Interface) driver, which could lead to a use-after-free. A local user could exploit this to     cause a denial of service (memory corruption or crash) or possibly for privilege escalation. This driver     is not enabled in Debian's official kernel configurations. CVE-2021-3772 A flaw was found in the SCTP     protocol implementation, which would allow a networked attacker to break an SCTP association. The attacker     would only need to know or guess the IP addresses and ports for the association. CVE-2021-4002 It was     discovered that hugetlbfs, the virtual filesystem used by applications to allocate huge pages in RAM, did     not flush the CPU's TLB in one case where it was necessary. In some circumstances a local user would be     able to read and write huge pages after they are freed and reallocated to a different process. This could     lead to privilege escalation, denial of service or information leaks. CVE-2021-4083 Jann Horn reported a     race condition in the local (Unix) sockets garbage collector, that can lead to use-after-free. A local     user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-4135 A flaw was found in the netdevsim driver which would lead to an     information leak. This driver is not enabled in Debian's official kernel configurations. CVE-2021-4155     Kirill Tkhai discovered a data leak in the way the XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for     a size increase of files with unaligned size. A local attacker can take advantage of this flaw to leak     data on the XFS filesystem. CVE-2021-4203 Jann Horn reported a race condition in the local (Unix) sockets     implementation that can lead to a use-after-free. A local user could exploit this to leak sensitive     information from the kernel. CVE-2021-20317 It was discovered that the timer queue structure could become     corrupt, leading to waiting tasks never being woken up. A local user with certain privileges could exploit     this to cause a denial of service (system hang). CVE-2021-20321 A race condition was discovered in the     overlayfs filesystem driver. A local user with access to an overlayfs mount and to its underlying upper     directory could exploit this for privilege escalation. CVE-2021-20322 An information leak was discovered     in the IPv4 implementation. A remote attacker could exploit this to quickly discover which UDP ports a     system is using, making it easier for them to carry out a DNS poisoning attack against that system.
    CVE-2021-22600 The syzbot tool found a flaw in the packet socket (AF_PACKET) implementation which could     lead to incorrectly freeing memory. A local user with CAP_NET_RAW capability (in any user namespace) could     exploit this for denial of service (memory corruption or crash) or possibly for privilege escalation.
    CVE-2021-28711, CVE-2021-28712, CVE-2021-28713 (XSA-391) Juergen Gross reported that malicious PV backends     can cause a denial of service to guests being serviced by those backends via high frequency events, even     if those backends are running in a less privileged environment. CVE-2021-28714, CVE-2021-28715 (XSA-392)     Juergen Gross discovered that Xen guests can force the Linux netback driver to hog large amounts of kernel     memory, resulting in denial of service. CVE-2021-38300 Piotr Krysiuk discovered a flaw in the classic BPF     (cBPF) JIT compiler for MIPS architectures. A local user could exploit this to excute arbitrary code in     the kernel. This issue is mitigated by setting sysctl net.core.bpf_jit_enable=0, which is the default. It     is *not* mitigated by disabling unprivileged use of eBPF. CVE-2021-39685 Szymon Heidrich discovered a     buffer overflow vulnerability in the USB gadget subsystem, resulting in information disclosure, denial of     service or privilege escalation. CVE-2021-39686 A race condition was discovered in the Android binder     driver, that could lead to incorrect security checks. On systems where the binder driver is loaded, a     local user could exploit this for privilege escalation. CVE-2021-39698 Linus Torvalds reported a flaw in     the file polling implementation, which could lead to a use-after-free. A local user could exploit this for     denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2021-39713 The     syzbot tool found a race condition in the network scheduling subsystem which could lead to a use-after-     free. A local user could exploit this for denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-41864 An integer overflow was discovered in the Extended BPF (eBPF)     subsystem. A local user could exploit this for denial of service (memory corruption or crash), or possibly     for privilege escalation. This can be mitigated by setting sysctl kernel.unprivileged_bpf_disabled=1,     which disables eBPF use by unprivileged users. CVE-2021-42739 A heap buffer overflow was discovered in the     firedtv driver for FireWire-connected DVB receivers. A local user with access to a firedtv device could     exploit this for denial of service (memory corruption or crash), or possibly for privilege escalation.
    CVE-2021-43389 The Active Defense Lab of Venustech discovered a flaw in the CMTP subsystem as used by     Bluetooth, which could lead to an out-of-bounds read and object type confusion. A local user with     CAP_NET_ADMIN capability in the initial user namespace could exploit this for denial of service (memory     corruption or crash), or possibly for privilege escalation. CVE-2021-43975 Brendan Dolan-Gavitt reported a     flaw in the hw_atl_utils_fw_rpc_wait() function in the aQuantia AQtion ethernet device driver which can     result in denial of service or the execution of arbitrary code. CVE-2021-43976 Zekun Shen and Brendan     Dolan-Gavitt discovered a flaw in the mwifiex_usb_recv() function of the Marvell WiFi-Ex USB Driver. An     attacker able to connect a crafted USB device can take advantage of this flaw to cause a denial of     service. CVE-2021-44733 A race condition was discovered in the Trusted Execution Environment (TEE)     subsystem for Arm processors, which could lead to a use-after-free. A local user permitted to access a TEE     device could exploit this for denial of service (memory corruption or crash) or possibly for privilege     escalation. CVE-2021-45095 It was discovered that the Phone Network protocol (PhoNet) driver has a     reference count leak in the pep_sock_accept() function. CVE-2021-45469 Wenqing Liu reported an out-of-     bounds memory access in the f2fs implementation if an inode has an invalid last xattr entry. An attacker     able to mount a specially crafted image can take advantage of this flaw for denial of service.
    CVE-2021-45480 A memory leak flaw was discovered in the __rds_conn_create() function in the RDS (Reliable     Datagram Sockets) protocol subsystem. CVE-2022-0001 (INTEL-SA-00598) Researchers at VUSec discovered that     the Branch History Buffer in Intel processors can be exploited to create information side channels with     speculative execution. This issue is similar to Spectre variant 2, but requires additional mitigations on     some processors. This can be exploited to obtain sensitive information from a different security context,     such as from user-space to the kernel, or from a KVM guest to the kernel. CVE-2022-0002 (INTEL-SA-00598)     This is a similar issue to CVE-2022-0001, but covers exploitation within a security context, such as from     JIT-compiled code in a sandbox to hosting code in the same process. This can be partly mitigated by     disabling eBPF for unprivileged users with the sysctl: kernel.unprivileged_bpf_disabled=2. This update     does that by default. CVE-2022-0322 Eiichi Tsukata discovered a flaw in the sctp_make_strreset_req()     function in the SCTP network protocol implementation which can result in denial of service. CVE-2022-0330     Sushma Venkatesh Reddy discovered a missing GPU TLB flush in the i915 driver, resulting in denial of     service or privilege escalation. CVE-2022-0435 Samuel Page and Eric Dumazet reported a stack overflow in     the networking module for the Transparent Inter-Process Communication (TIPC) protocol, resulting in denial     of service or potentially the execution of arbitrary code. CVE-2022-0487 A use-after-free was discovered     in the MOXART SD/MMC Host Controller support driver. This flaw does not impact the Debian binary packages     as CONFIG_MMC_MOXART is not set. CVE-2022-0492 Yiqi Sun and Kevin Wang reported that the cgroup-v1     subsystem does not properly restrict access to the release-agent feature. A local user can take advantage     of this flaw for privilege escalation and bypass of namespace isolation. CVE-2022-0617 butt3rflyh4ck     discovered a NULL pointer dereference in the UDF filesystem. A local user that can mount a specially     crafted UDF image can use this flaw to crash the system. CVE-2022-0644 Hao Sun reported a missing check     for file read permission in the finit_module() and kexec_file_load() system calls. The security impact of     this is unclear, since these system calls are usually only available to the root user. CVE-2022-22942 It     was discovered that wrong file file descriptor handling in the VMware Virtual GPU driver (vmwgfx) could     result in information leak or privilege escalation. CVE-2022-24448 Lyu Tao reported a flaw in the NFS     implementation in the Linux kernel when handling requests to open a directory on a regular file, which     could result in a information leak. CVE-2022-24959 A memory leak was discovered in the     yam_siocdevprivate() function of the YAM driver for AX.25, which could result in denial of service.
    CVE-2022-25258 Szymon Heidrich reported the USB Gadget subsystem lacks certain validation of interface OS     descriptor requests, resulting in memory corruption. CVE-2022-25375 Szymon Heidrich reported that the     RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command, resulting in information leak     from kernel memory.
