-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel-rt security and bug fix update Advisory ID: RHSA-2023:4814-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:4814 Issue date: 2023-08-29 CVE Names: CVE-2022-1353 CVE-2022-39188 CVE-2023-0458 CVE-2023-3090 CVE-2023-28466 ===================================================================== 1. Summary: An update for kernel-rt is now available for Red Hat Enterprise Linux 9.0 Extended Update Support. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Real Time EUS (v.9.0) - x86_64 Red Hat Enterprise Linux Real Time for NFV EUS (v.9.0) - x86_64 3. Description: 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: ipvlan: out-of-bounds write caused by unclear skb->cb (CVE-2023-3090) * 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): * kernel-rt: update RT source tree to the latest RHEL-9.0.z11 Batch (BZ#2219867) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
