Summary
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c (CVE-2022-3564)
* kernel: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378)
* kernel: use-after-free in __nfs42_ssc_open() in fs/nfs/nfs4file.c leading to remote Denial of Service attack (CVE-2022-4379)
* kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan (CVE-2023-0179)
* kernel: an out-of-bounds vulnerability in i2c-ismt driver (CVE-2022-2873)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* kernel-rt: update RT source tree to the latest AlmaLinux-9.1.z2 Batch (BZ#2160463)
