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

  - In io_identity_cow of io_uring.c, there is a possible way to corrupt memory due to a use after free. 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-238177383References:
    Upstream kernel (CVE-2022-20409)

  - In emulation_proc_handler of armv8_deprecated.c, there is a possible way to corrupt memory 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-237540956References: Upstream kernel (CVE-2022-20422)

  - In rndis_set_response of rndis.c, there is a possible out of bounds write due to an integer overflow. This
    could lead to local escalation of privilege if a malicious USB device is attached with no additional
    execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions:
    Android kernelAndroid ID: A-239842288References: Upstream kernel (CVE-2022-20423)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers
    em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system
    or potentially escalate their privileges on the system. (CVE-2022-3239)

  - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead
    to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or
    member of the audio group) could use this flaw to crash the system, resulting in a denial of service
    condition (CVE-2022-3303)

  - A vulnerability classified as problematic has been found in Linux Kernel. This affects the function
    fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to
    out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to
    fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is an unknown
    function of the file mm/memory.c of the component Driver Handler. The manipulation leads to use after
    free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
    The identifier of this vulnerability is VDB-211020. (CVE-2022-3523)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this
    vulnerability is the function ipv6_renew_options of the component IPv6 Handler. The manipulation leads to
    memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue.
    The identifier VDB-211021 was assigned to this vulnerability. (CVE-2022-3524)

  - A vulnerability classified as critical has been found in Linux Kernel. Affected is the function
    btf_dump_name_dups of the file tools/lib/bpf/btf_dump.c of the component libbpf. The manipulation leads to
    use after free. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability
    is VDB-211032. (CVE-2022-3534)

  - A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability
    is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the
    component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this
    issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)

  - A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function
    tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It
    is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this
    vulnerability. (CVE-2022-3566)

  - A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects
    the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to
    race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier
    assigned to this vulnerability. (CVE-2022-3567)

  - An out-of-bounds memory write flaw was found in the Linux kernel's Kid-friendly Wired Controller driver.
    This flaw allows a local user to crash or potentially escalate their privileges on the system. It is in
    bigben_probe of drivers/hid/hid-bigbenff.c. The reason is incorrect assumption - bigben devices all have
    inputs. However, malicious devices can break this assumption, leaking to out-of-bound write.
    (CVE-2022-3577)

  - A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the sch_sfb
    enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed)
    into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of
    service. (CVE-2022-3586)

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. This affects the
    function find_prog_by_sec_insn of the file tools/lib/bpf/libbpf.c of the component BPF. The manipulation
    leads to null pointer dereference. It is recommended to apply a patch to fix this issue. The identifier
    VDB-211749 was assigned to this vulnerability. (CVE-2022-3606)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this
    vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation
    leads to race condition. The attack can be launched remotely. It is recommended to apply a patch to fix
    this issue. The identifier VDB-211921 was assigned to this vulnerability. (CVE-2022-3623)

  - A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function
    devlink_param_set/devlink_param_get of the file net/core/devlink.c of the component IPsec. The
    manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier
    VDB-211929 was assigned to this vulnerability. (CVE-2022-3625)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. This vulnerability affects
    the function vsock_connect of the file net/vmw_vsock/af_vsock.c. The manipulation leads to memory leak. It
    is recommended to apply a patch to fix this issue. VDB-211930 is the identifier assigned to this
    vulnerability. (CVE-2022-3629)

  - 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)

  - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of
    service can occur upon binding to an already bound chain. (CVE-2022-39190)

  - roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition
    and resultant use-after-free in certain situations where a report is received while copying a
    report->value is in progress. (CVE-2022-41850)

  - mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
    (CVE-2022-42703)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-
    space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary
    speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816)
    (CVE-2022-2602)

  - ** 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-2022-42432)
