Summary

Moderate: 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): * information leak in scsi_ioctl() (CVE-2022-0494) * use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055) 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): * Power9 - LPAR fails to boot in shared processing mode and call traces are seen [Hash] (BZ#2092248) * Hard lockups are observed while running stress-ng and LPAR hangs (BZ#2092253) * FIPS module identification via name and version (BZ#2093384) * gfs2: File corruption with large writes when memory is tight (BZ#2097306) * i/o on initiator stuck when network is disrupted (4.18.0-372.9.1.el8.x86_64) (BZ#2098251) * AlmaLinux 9.1 doesn't support 3rd SATA (BZ#2099740) * Guest call trace when reboot after postcopy migration with high stress workload (BZ#2100903) * Oops or general protection fault with RIP decode_attr_security_label at decode_getfattr_attrs (BZ#2101854) * Oops as BUG: unable to handle page fault as free of uninitialized nfs4_label on nfs referral lookup (BZ#2101858) * lpar crash with Oops: Kernel access of bad area, sig: 11 [#1] when changing mtu of a bond interface (P10/ ibmvnic/ Haleakala) (BZ#2103085) * OS doesn't boot when vmd and interrupt remapping are enabled (BZ#2109974) Enhancement(s): * iommu/vt-d: Make DMAR_UNITS_SUPPORTED a config setting (BZ#2105326)

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.
