* kernel: kernel info leak issue in pfkey_register (CVE-2022-1353)

* kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry (CVE-2022-39188)

* kernel: speculative pointer dereference in do_prlimit() in kernel/sys.c (CVE-2023-0458)

* kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference (CVE-2023-28466)

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):

* IOMMU/DMA updates for 9.1 (BZ#2192629)

* rbd: avoid fast-diff corruption in snapshot-based mirroring (BZ#2216570)

* Hyper-V RHEL-9: Fix VM crash/hang Issues due to fast VF add/remove events (BZ#2217067)

* KVM: x86: fix sending PV IPI (BZ#2225337)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2023:4801.
