Summary: An update for kernel-rt is now available for Red Hat Enterprise Linux 9. 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 (v. 9) - x86_64 Red Hat Enterprise Linux Real Time for NFV (v. 9) - 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: watch queue race condition can lead to privilege escalation (CVE-2022-2959) * kernel: memory corruption in AX88179_178A based USB ethernet device. (CVE-2022-2964) * kernel: i915: Incorrect GPU TLB flush can lead to random memory access (CVE-2022-4139) * kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945) * kernel: i2c: unbounded length leads to buffer overflow in ismt_access() (CVE-2022-3077) * kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594) 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): * DELL EMC: System is not booting into RT Kernel with perc12 [kernel-rt] (BZ#2139863) * kernel-rt: update RT source tree to the latest RHEL-9.1.z1 Batch (BZ#2141817) 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.
