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.
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: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378)
* ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266)
* kernel: FUSE filesystem low-privileged user privileges escalation (CVE-2023-0386)
* kernel: net: CPU soft lockup in TC mirred egress-to-ingress action (CVE-2022-4269)
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):
* Lazy irq_work does not raise softirq on PREEMPT_RT [rhel-8] (BZ#2172163)
* The latest RHEL 8.7.z3 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2172278)
