"The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2022:3930-1 advisory.

  - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that
    allows local users to create files for the XFS file-system with an unintended group ownership and with
    group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a
    certain group and is writable by a user who is not a member of this group. This can lead to excessive
    permissions granted in case when they should not. This vulnerability is similar to the previous
    CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

  - 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)

  - 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 vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects
    the function kcm_tx_work of the file net/kcm/kcmsock.c of the component kcm. The manipulation leads to
    race condition. It is recommended to apply a patch to fix this issue. VDB-211018 is the identifier
    assigned to this vulnerability. (CVE-2022-3521)

  - 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 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 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 vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function
    nilfs_bmap_lookup_at_level of the file fs/nilfs2/inode.c of the component nilfs2. The manipulation leads
    to null pointer dereference. 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-211920. (CVE-2022-3621)

  - 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. It
    is recommended to apply a patch to fix this issue. VDB-211930 is the identifier assigned to this
    vulnerability. (CVE-2022-3629)

  - A vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects
    the function nilfs_attach_log_writer of the file fs/nilfs2/segment.c of the component BPF. The
    manipulation leads to memory leak. The attack may be initiated remotely. It is recommended to apply a
    patch to fix this issue. The identifier VDB-211961 was assigned to this vulnerability. (CVE-2022-3646)

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function
    nilfs_new_inode of the file fs/nilfs2/inode.c of the component BPF. 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-211992. (CVE-2022-3649)

  - 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)
