An update that solves 13 vulnerabilities and has three fixes can now be
installed.

## Description:

The SUSE Linux Enterprise 12 SP4 LTSS kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed:

  * CVE-2022-3566: Fixed race condition in the TCP Handler (bsc#1204405).
  * CVE-2022-45886: Fixed a .disconnect versus dvb_device_open race condition in
    dvb_net.c that lead to a use-after-free (bsc#1205760).
  * CVE-2022-45885: Fixed a race condition in dvb_frontend.c that could cause a
    use-after-free when a device is disconnected (bsc#1205758).
  * CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack of a
    dvb_frontend_detach call (bsc#1205762).
  * CVE-2022-45919: Fixed a use-after-free in dvb_ca_en50221.c that could occur
    if there is a disconnect after an open, because of the lack of a wait_event
    (bsc#1205803).
  * CVE-2022-45884: Fixed a use-after-free in dvbdev.c, related to
    dvb_register_device dynamically allocating fops (bsc#1205756).
  * CVE-2023-31084: Fixed a blocking issue in drivers/media/dvb-
    core/dvb_frontend.c (bsc#1210783).
  * CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because
    lmax can exceed QFQ_MIN_LMAX (bsc#1210940 bsc#1211260).
  * CVE-2023-2194: Fixed an out-of-bounds write vulnerability in the SLIMpro I2C
    device driver (bsc#1210715).
  * CVE-2023-32269: Fixed a use-after-free in af_netrom.c, related to the fact
    that accept() was also allowed for a successfully connected AF_NETROM socket
    (bsc#1211186).
  * CVE-2023-1380: A slab-out-of-bound read problem was fixed in
    brcmf_get_assoc_ies(), that could lead to a denial of service (bsc#1209287).
  * CVE-2023-2513: A use-after-free vulnerability was fixed in the ext4
    filesystem, related to the way it handled the extra inode size for extended
    attributes (bsc#1211105).
  * CVE-2023-2176: A vulnerability was found in compare_netdev_and_ip in
    drivers/infiniband/core/cma.c in RDMA. The improper cleanup results in out-
    of-boundary read, where a local user can utilize this problem to crash the
    system or escalation of privilege (bsc#1210629).

The following non-security bugs were fixed:

  * ext4: add EXT4_INODE_HAS_XATTR_SPACE macro in xattr.h (bsc#1206878).
  * ipv6: sr: fix out-of-bounds read when setting HMAC data (bsc#1211592).
