An update that solves 17 vulnerabilities and has seven security fixes can now be
installed.

## Description:

The SUSE Linux Enterprise 15 SP4 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

  * CVE-2023-4563: Fixed an use-after-free flaw in the nftables sub-component.
    This vulnerability could allow a local attacker to crash the system or lead
    to a kernel information leak problem. (bsc#1214727)
  * CVE-2023-39194: Fixed a flaw in the processing of state filters which could
    allow a local attackers to disclose sensitive information. (bsc#1215861)
  * CVE-2023-39193: Fixed a flaw in the processing of state filters which could
    allow a local attackers to disclose sensitive information. (bsc#1215860)
  * CVE-2023-39192: Fixed a flaw in the u32_match_it function which could allow
    a local attackers to disclose sensitive information. (bsc#1215858)
  * CVE-2023-42754: Fixed a null pointer dereference in ipv4_link_failure which
    could lead an authenticated attacker to trigger a DoS. (bsc#1215467)

    component which could be exploited to achieve local privilege escalation.
    (bsc#1215899)
  * CVE-2023-4155: Fixed a flaw in KVM AMD Secure Encrypted Virtualization
    (SEV). An attacker can trigger a stack overflow and cause a denial of
    service or potentially guest-to-host escape in kernel configurations without
    stack guard pages. (bsc#1214022)

    table. A user located in the local network or with a high bandwidth
    connection can increase the CPU usage of the server that accepts IPV6
    connections up to 95% (bsc#1212703).

    could be exploited to crash the system (bsc#1210169).
  * CVE-2023-4881: Fixed a out-of-bounds write flaw in the netfilter subsystem
    that could lead to potential information disclosure or a denial of service
    (bsc#1215221).
  * CVE-2023-2177: Fixed a null pointer dereference issue in the sctp network
    protocol which could allow a user to crash the system (bsc#1210643).
