SUSE-SU-2024:0120-1: Security update for the Linux Kernel
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 BDADDR 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 btsockioctl race condition in btsockrecvmsg (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 smb2dumpdetail 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)

Frequently Asked Questions
Which deployments are covered by this update?
The update applies to SUSE Linux Enterprise 15 SP1 systems using the listed kernel packages, including kernel-default and associated development, debug, symbol, and build packages.
Which issues have explicit attacker-access requirements?
The Bluetooth pairing issue involves an unauthenticated nearby device during legacy BR/EDR PIN-code pairing. The SMB out-of-bounds read issues are described as exploitable by a local attacker; no access prerequisite is stated for the other listed issues.
What impacts are explicitly described for the affected components?
The SMB issues could allow a local attacker to crash the system or leak internal kernel information. The NVMe-oF/TCP issue could lead to an information leak, while the Bluetooth issue could allow pairing by spoofing the peer device's BD_ADDR without knowing the PIN.
