"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - In xfrm6_tunnel_free_spi of net/ipv6/xfrm6_tunnel.c, there is a possible use after free due to improper
    locking. 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-168043318
    (CVE-2020-27066)

  - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to
    a heap buffer 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-173843328References: Upstream kernel (CVE-2021-0512)

  - In fs/eventpoll.c, there is a possible 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-204450605References: Upstream kernel (CVE-2021-39634)

  - An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux
    Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.
    (CVE-2022-0812)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-
    component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user
    forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local
    user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

  - 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)

  - 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)

  - 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)

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn
    by its CNA. Further investigation showed that it was not a security issue. Notes: none. (CVE-2022-3542)

  - 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 critical, has been found in Linux Kernel. Affected by this issue
    is the function del_timer of the file drivers/isdn/mISDN/l1oip_core.c of the component Bluetooth. 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-211088. (CVE-2022-3565)

  - 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)

  - 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 declared as problematic. Affected by this
    vulnerability is the function intr_callback of the file drivers/net/usb/r8152.c of the component BPF. The
    manipulation leads to logging of excessive data. The attack can be launched remotely. It is recommended to
    apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211363.
    (CVE-2022-3594)

  - A buffer overflow flaw was found in the Linux kernel Broadcom Full MAC Wi-Fi driver. This issue occurs
    when a user connects to a malicious USB device. This can allow a local user to crash the system or
    escalate their privileges. (CVE-2022-3628)

  - 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.
    The complexity of an attack is rather high. The exploitation appears to be difficult. 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)

  - drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information
    from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
    (CVE-2022-40768)

  - A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in
    drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and
    gain escalation of privileges. (CVE-2022-4095)

  - 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)
