Red Hat Security Advisory: kernel-rt security update
Red Hat has issued a security advisory for kernel-rt packages, which provide the Real Time Linux Kernel for systems requiring high determinism. The update addresses two vulnerabilities: CVE-2024-26935, a regression involving an unremoved procfs host directory in the SCSI core, and CVE-2024-50275, which discards stale CPU state when handling SVE traps on arm64 architectures. The advisory rates the security impact as moderate. Systems must be rebooted after applying the update for it to take effect.
AI Analysis
Technical Summary
This advisory covers security fixes in the Red Hat kernel-rt packages for Red Hat Enterprise Linux 8 Real Time variants. The first fix (CVE-2024-26935) resolves a regression where a procfs host directory was not properly removed in the SCSI core subsystem. The second fix (CVE-2024-50275) addresses stale CPU state handling during Scalable Vector Extension (SVE) traps on arm64 processors. These fixes mitigate potential issues related to kernel state consistency and resource cleanup. The update is rated moderate in severity by Red Hat Product Security. No CVSS scores are provided in the advisory. The update requires a system reboot to apply.
Potential Impact
The vulnerabilities fixed involve kernel subsystems that could affect system stability or correctness. CVE-2024-26935 addresses a regression causing an unremoved procfs directory, which could lead to resource leakage or inconsistent system state. CVE-2024-50275 mitigates stale CPU state handling on arm64 SVE traps, potentially preventing incorrect CPU state processing. The advisory rates the overall impact as moderate. There are no known exploits in the wild reported at this time.
Mitigation Recommendations
Red Hat has released updated kernel-rt packages for affected Red Hat Enterprise Linux 8 Real Time variants. Users should apply the security update as described in Red Hat's official guidance (https://access.redhat.com/articles/11258). A system reboot is required to activate the fixes. No additional mitigation steps are indicated by the vendor.
