An update that solves eight vulnerabilities, contains one feature and has one
security fix can now be installed.

## Description:

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

  * CVE-2020-26555: Fixed Bluetooth legacy BR/EDR PIN code pairing in Bluetooth
    Core Specification 1.0B that may permit an unauthenticated nearby device to
    spoof the BD_ADDR of the peer device to complete pairing without knowledge
    of the PIN (bsc#1179610 bsc#1215237).
  * CVE-2022-2586: Fixed a use-after-free which can be triggered when a nft
    table is deleted (bsc#1202095).
  * CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race
    condition in bt_sock_recvmsg (bsc#1218559).
  * CVE-2023-6121: Fixed an out-of-bounds read vulnerability in the NVMe-oF/TCP
    subsystem that could lead to information leak (bsc#1217250).
  * CVE-2023-6606: Fixed an out-of-bounds read vulnerability in smbCalcSize in
    fs/smb/client/netmisc.c that could allow a local attacker to crash the
    system or leak internal kernel information (bsc#1217947).
  * CVE-2023-6610: Fixed an out-of-bounds read vulnerability in smb2_dump_detail
    in fs/smb/client/smb2ops.c that could allow a local attacker to crash the
    system or leak internal kernel information (bsc#1217946).
  * CVE-2023-6931: Fixed a heap out-of-bounds write vulnerability in the Linux
    kernel's Performance Events system component that could lead to local
    privilege escalation. (bsc#1218258).
  * CVE-2023-6932: Fixed a use-after-free vulnerability in the Linux kernel's
    ipv4: igmp component that could lead to local privilege escalation
    (bsc#1218253).

The following non-security bugs were fixed:

  * doc/README.SUSE: Add how to update the config for module signing
    (jsc#PED-5021)
  * doc/README.SUSE: Remove how to build modules using kernel-source
    (jsc#PED-5021)
  * doc/README.SUSE: Simplify the list of references (jsc#PED-5021)

## Special Instructions and Notes:

  * Please reboot the system after installing this update.
