-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2022:6872-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2022:6872 Issue date: 2022-10-11 CVE Names: CVE-2022-2588 CVE-2022-21123 CVE-2022-21125 CVE-2022-21166 ==================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 8.1 Update Services for SAP Solutions. 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 BaseOS E4S (v. 8.1) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123) * Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125) * Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166) 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. 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. Bugs fixed (https://bugzilla.redhat.com/): 2090237 - CVE-2022-21123 hw: cpu: Incomplete cleanup of multi-core shared buffers (aka SBDR) 2090240 - CVE-2022-21125 hw: cpu: Incomplete cleanup of microarchitectural fill buffers (aka SBDS) 2090241 - CVE-2022-21166 hw: cpu: Incomplete cleanup in specific special register write operations (aka DRPW) 2114849 - CVE-2022-2588 kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation 6.
