Summary: An update for kernel is now available for Red Hat Enterprise Linux 8.4 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 CodeReady Linux Builder EUS (v. 8.4) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS EUS (v.8.4) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. The following packages have been upgraded to a later upstream version: kernel (4.18.0). Security Fix(es): * A use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * Information leak in the IPv6 implementation (CVE-2021-45485) * Information leak in the IPv4 implementation (CVE-2021-45486) * 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. Bug Fix(es): * DR, Ignore modify TTL if ConnectX-5 doesn't support it (BZ#2075549) * execve exit tracepoint not called (BZ#2106663) * Unable to boot RHEL-8.6 on Brazos max. config (Install is success) (BZ#2107475) * "vmcore failed, _exitcode:139" error observed while capturing vmcore during fadump after memory remove. incomplete vmcore is captured. (BZ#2107490) * soft lockups under heavy I/O load to ahci connected SSDs (BZ#2110773) * Allow substituting custom vmlinux.h for the build (BZ#2116407) 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.

Software Description: - linux-oem-5.17: Linux kernel for OEM systems Details: It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, 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. (CVE-2022-1679) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1789) Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle an illegal instruction in a guest, resulting in a null pointer dereference. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1852) Gerald Lee discovered that the NTFS file system implementation in the Linux kernel did not properly handle certain error conditions, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2022-1973) It was discovered that the netfilter subsystem in the Linux kernel contained a buffer overflow in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2078) It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. 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) It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-34494, CVE-2022-34495) Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1652) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.17.0-1013-oem 5.17.0-1013.14 linux-image-oem-22.04 5.17.0.1013.12 linux-image-oem-22.04a 5.17.0.1013.12 After a standard system update you need to reboot your computer to make all the necessary changes. 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.

CVE-2022-21123, CVE-2022-21125, CVE-2022-21127, CVE-2022-21166 Various researchers discovered flaws in Intel processors, collectively referred to as MMIO Stale Data vulnerabilities, which may result in information leak to local users. For details please refer to https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/processor-mmio-stale-data-vulnerabilities.html CVE-2022-21151 Alysa Milburn, Jason Brandt, Avishai Redelman and Nir Lavi discovered that for some Intel processors optimization removal or modification of security-critical code may result in information disclosure to local users. For the oldstable distribution (buster), these problems have been fixed in version 3.20220510.1~deb10u1. For the stable distribution (bullseye), these problems have been fixed in version 3.20220510.1~deb11u1. We recommend that you upgrade your intel-microcode packages.
