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

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

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel     (CVE-2022-20368)

  - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to     restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently     allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass     verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and     unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for     peripherals that do not verify firmware updates. We recommend upgrading past commit     4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)

  - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
    (CVE-2022-2964)

  - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations. (CVE-2022-39189)

  - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation     (CVE-2022-2586)

  - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation     (CVE-2022-2588)

    A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in     the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the     time of table deletion, possibly leading to local privilege escalation.

    CVE-2022-2588:
    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem.

    CVE-2022-26365:
    Linux disk/nic frontends data leaks [This 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-2022-2639:
    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2022-28893:
    The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state.

    CVE-2022-29581:
    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-2022-2959:
    A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().
    The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper     locking when performing operations on an object. This flaw allows a local user to crash the system or     escalate their privileges on the system.

    CVE-2022-2978:
    A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system.

    CVE-2022-29900:
    Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution     under certain microarchitecture-dependent conditions.

    CVE-2022-29901:
    Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their     retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can     hijack return instructions to achieve arbitrary speculative code execution under certain     microarchitecture-dependent conditions.

    CVE-2022-32250:
    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-2022-32296:
    The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are     used.

    CVE-2022-32981:
    An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer     overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point     registers.

    CVE-2022-33740:
    Linux disk/nic frontends data leaks [This 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-2022-33741:
    Linux disk/nic frontends data leaks [This 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).

    CVE-2022-33981:
    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-2022-34918:
    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-2022-36123:
    The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This     allows Xen PV guest OS users to cause a denial of service or gain privileges.

    CVE-2022-36879:
    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice.

    CVE-2022-36946:
    nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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

An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.
