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: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)
* kernel: information leak in scsi_ioctl() (CVE-2022-0494)
* Kernel: A kernel-info-leak issue in pfkey_register (CVE-2022-1353)
* hw: cpu: AMD: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816, CVE-2022-29900)
* hw: cpu: AMD: Branch Type Confusion (non-retbleed) (CVE-2022-23825)
* hw: cpu: Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901)
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):
* [rhel8-rt] BUG: using __this_cpu_add() in preemptible [00000000] - caller is __mod_memcg_lruvec_state+0x69/0x1c0 (BZ#2122600)
* The latest RHEL 8.6.z4 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2125396)
