An update that solves seven vulnerabilities, contains one feature and has two security 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-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-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 in the SMB client when receiving a malformed length from a server (bsc#1217947).
• CVE-2023-6610: Fixed an out of bounds read in the SMB client when printing debug 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)
• io_uring: fix 32-bit compatability with sendmsg/recvmsg (bsc#1217709).
