Summary
Important: kernel-rt security, bug fix, and enhancement update
Details
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: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset (CVE-2025-68745)
- kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show() (CVE-2026-46149)
- kernel: netfilter: nf_log: validate MAC header was set before dumping it (CVE-2026-52942)
- kernel: sctp: diag: reject stale associations in dump_one path (CVE-2026-52917)
- kernel: net: pull headers in qdisc_pkt_len_segs_init() (CVE-2026-53091)
- kernel: netfilter: nf_conntrack_sip: don't use simple_strtoul (CVE-2026-52986)
- kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing (CVE-2026-53246)
- kernel: tipc: fix slab-use-after-free Read in tipc_aead_decrypt_done (CVE-2026-63801)
- kernel: sctp: fix race between sctp_wait_for_connect and peeloff (CVE-2026-63971)
- kernel: security/keys: fix missed RCU read section on lookup (CVE-2026-64015)
- kernel: ixgbevf: fix use-after-free in VEPA multicast source pruning (CVE-2026-64113)
- kernel: sctp: fix auth_hmacs array size in struct sctp_cookie (CVE-2026-68376)
- kernel: tipc: clear sock->sk on the failed-insert path in tipc_sk_create() (CVE-2026-68117)
- kernel: sctp: auth: verify auth requirement when auth_chunk is NULL (CVE-2026-68300)
- kernel: sctp: validate stream count in sctp_process_strreset_inreq() (CVE-2026-68315)
Bug Fix(es) and Enhancement(s):
- scsi: mpt3sas: avoid freeing unallocated PCIe SGL buffers [almalinux 8.6.z] (JIRA:AlmaLinux-194117)
- gfs2: harden gfs2_glock_hold [AlmaLinux-8] (JIRA:AlmaLinux-240340)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
