An update that solves 15 vulnerabilities and has five fixes can now be
installed.

## Description:

The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

  * CVE-2023-1872:Fixed a use after free vulnerability in the io_uring
    subsystem, which could lead to local privilege escalation (bsc#1210414).
  * CVE-2022-2196: Fixed a regression related to KVM that allowed for
    speculative execution attacks (bsc#1206992).
  * CVE-2023-1670: Fixed a use after free in the Xircom 16-bit PCMCIA Ethernet
    driver. A local user could use this flaw to crash the system or potentially
    escalate their privileges on the system (bsc#1209871).
  * CVE-2023-2162: Fixed an use-after-free flaw in iscsi_sw_tcp_session_create
    (bsc#1210647).
  * 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).
  * CVE-2023-1998: Fixed a use after free during login when accessing the shost
    ipaddress (bsc#1210506).
  * CVE-2023-30772: Fixed a race condition and resultant use-after-free in
    da9150_charger_remove (bsc#1210329).
  * CVE-2023-2008: A flaw was found in the fault handler of the udmabuf device
    driver. An attacker can leverage this vulnerability to escalate privileges
    and execute arbitrary code (bsc#1210453).
  * CVE-2023-1855: Fixed a use after free in xgene_hwmon_remove (bsc#1210202).
  * CVE-2020-36691: Fixed a denial of service (unbounded recursion)
    vulnerability via a nested Netlink policy with a back reference (bsc#1209613
    bsc#1209777).
  * CVE-2023-1990: Fixed a use after free in ndlc_remove (bsc#1210337).
  * CVE-2023-1989: Fixed a use after free in btsdio_remove (bsc#1210336).
  * CVE-2022-43945: Fixed a buffer overflow in the NFSD implementation
    (bsc#1205128).
  * CVE-2023-1611: Fixed an use-after-free flaw in btrfs_search_slot
    (bsc#1209687).
  * CVE-2023-1838: Fixed an use-after-free flaw in virtio network subcomponent.
    This flaw could allow a local attacker to crash the system and lead to a
    kernel information leak problem. (bsc#1210203).

The following non-security bugs were fixed:

  * Drivers: vmbus: Check for channel allocation before looking up relids (git-
    fixes).
  * Replace mkinitrd dependency with dracut (bsc#1202353).
  * cifs: fix negotiate context parsing (bsc#1210301).
