-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2023:3852-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:3852 Issue date: 2023-06-27 CVE Names: CVE-2023-1281 CVE-2023-32233 ==================================================================== 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): * kernel: tcindex: use-after-free vulnerability in traffic control index filter allows privilege escalation (CVE-2023-1281) * kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233) 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): * Invalid character detected by rpminspect in Documentation/translations/zh_CN/process/magic-number.rst (BZ#2208289) 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/): 2181847 - CVE-2023-1281 kernel: tcindex: use-after-free vulnerability in traffic control index filter allows privilege escalation 2196105 - CVE-2023-32233 kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation 6.
