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

The remote OracleVM system is missing necessary patches to address security updates:

  - In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum     address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP     platforms. This is related to a capability check for the wrong task. (CVE-2019-9213)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - 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)

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

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

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - In several functions of binder.c, there is a possible way to represent the wrong domain to SELinux due to     a race condition. 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-200688826References: Upstream kernel (CVE-2021-39686)

  - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency     use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker     could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the     system. (CVE-2022-1652)

  - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP     pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use     after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

  - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds     read due to improper input validation. This could lead to local information disclosure if a malicious USB     HID device were plugged in, with no additional execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream     kernel (CVE-2022-20132)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead     to local escalation of privilege with System execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream     kernel (CVE-2022-20154)

  - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer     overflow. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-182388481References: Upstream kernel (CVE-2022-20166)

  - A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

  - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that     allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)

  - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text     explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device     frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).
    Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to     unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend     (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

  - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are     used. This occurs because of use of Algorithm 4 ('Double-Hash Port Selection Algorithm') of RFC 6056.
    (CVE-2022-32296)

  - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree     to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the     related lock held, resulting in a small race window, which can be used by unprivileged guests via PV     devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS)     of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory     pages. (CVE-2022-33744)

  - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of     a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
    (CVE-2022-33981)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)
