Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.2 Telecommunications Update Service.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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: ipvlan: out-of-bounds write caused by unclear skb->cb (CVE-2023-3090)
* kernel: cls_flower: out-of-bounds write in fl_set_geneve_opt() (CVE-2023-35788)
* kernel: OOB access in the Linux kernel's XFS subsystem (CVE-2023-2124)
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 RHEL-8.2.z28 source tree (BZ#2228917)
