TITLE

Red Hat Security Advisory 2022-6872-01

DESCRIPTION

Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. 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. 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. 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. Package List: Red Hat Enterprise Linux BaseOS E4S (v. Our key and details on how to verify the signature are available from https://access.redhat.com/security/team/key/ 7. ========================================================================== Ubuntu Security Notice USN-5484-1 June 16, 2022 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel. A privileged attacker could use this to bypass UEFI Secure Boot restrictions. (CVE-2022-21499) It was discovered that a race condition existed in the network scheduling subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123) It was discovered that some Intel processors did not completely perform cleanup actions on microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21125) It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: linux-image-3.13.0-190-generic 3.13.0-190.241 linux-image-3.13.0-190-lowlatency 3.13.0-190.241 linux-image-generic 3.13.0.190.199 linux-image-lowlatency 3.13.0.190.199 linux-image-server 3.13.0.190.199 linux-image-virtual 3.13.0.190.199 Please note that fully mitigating processor vulnerabilities requires corresponding processor microcode/firmware updates. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
