ALSA-2026:59737 · Important: kernel-rt security, bug fix, and enhancement update
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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: sctp: purge outqueue on stale COOKIE-ECHO handling (CVE-2026-52924) * kernel: scsi: target: iscsi: Validate CHAP_R length before base64 decode (CVE-2026-63886) * kernel: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check (CVE-2026-63913) * kernel: i2c: stub: Reject I2C block transfers with invalid length (CVE-2026-64191) * kernel: netfilter: ipset: fix race between dump and ip_set_list resize (CVE-2026-64189) * kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page (CVE-2026-64320) * kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count (CVE-2026-64277) * kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count (CVE-2026-64276) Bug Fix(es) and Enhancement(s): * [AlmaLinux-RT] usb_hub_wq items may run on isolated+nohz_full cores (JIRA:AlmaLinux-178088) * SELinux TCP/MPTCP connect check bypass via TCP Fast Open [almalinux-8.10.z] (JIRA:AlmaLinux-222800) * ss core dumped when there is an SCTP session [almalinux-8.10.z] (JIRA:AlmaLinux-212400) 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.
