Summary

Important: kernel security, bug fix, and enhancement update

Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

posix cpu timer use-after-free may lead to local privilege escalation (CVE-2022-2585)
Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594)

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 crash after reboot of T14/G2 AMD laptop (mt7921e module) (BZ#2095653)
execve exit tracepoint not called (BZ#2106661)
Matrox black screen on VGA output on some systems. (BZ#2112017)
The kernel needs to offer a way to reseed the Crypto DRBG and atomically extract random numbers from it (BZ#2121129)
watchdog BUG: soft lockup - CPU#30 stuck for 34s! [swapper/30:0] (BZ#2127857)
Update cifs to 5.16 (BZ#2127858)
Bad page state in process qemu-kvm pfn:68a74600 (BZ#2127859)
vfio zero page mappings fail after 2M instances (BZ#2128791)
The kernel needs to offer a way to reseed the Crypto DRBG and atomically extract random numbers from it (part 2) (BZ#2128970)

Enhancement(s):

Need to enable hpilo to support new HPE RL300 Gen11 for ARM (aarch64) (BZ#2129453)

Detection rules are retrieved from Rulezet.

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.
