What to do
AI-suggested
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.
Description
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.
