## Description:

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

The following security bugs were fixed:

    that could cause a local DoS. (bsc#1210778)
  * CVE-2023-45862: Fixed an issue in the ENE UB6250 reader driver whwere an
    object could potentially extend beyond the end of an allocation causing.
    (bsc#1216051)
  * CVE-2023-2163: Fixed an incorrect verifier pruning in BPF that could lead to
    unsafe code paths being incorrectly marked as safe, resulting in arbitrary
    read/write in kernel memory, lateral privilege escalation, and container
    escape. (bsc#1215518)
  * CVE-2023-34324: Fixed a possible deadlock in Linux kernel event handling.
    (bsc#1215745).
  * CVE-2023-39189: Fixed a flaw in the Netfilter subsystem that could allow a
    local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read,
    leading to a crash or information disclosure. (bsc#1216046)
  * CVE-2023-3111: Fixed a use-after-free vulnerability in prepare_to_relocate
    in fs/btrfs/relocation.c (bsc#1212051).
  * CVE-2023-39194: Fixed an out of bounds read in the XFRM subsystem
    (bsc#1215861).
  * CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem
    (bsc#1215860).
  * CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858).
  * CVE-2023-42754: Fixed a NULL pointer dereference in the IPv4 stack that
    could lead to denial of service (bsc#1215467).

The following non-security bugs were fixed:

  * KVM: x86: fix sending PV IPI (git-fixes, bsc#1210853, bsc#1216134).
  * bpf: propagate precision in ALU/ALU64 operations (git-fixes).
