CVE-2024-42135

CVE-2024-42135 concerns the Linux kernel vhost_task handling of SIGKILL. The connected sources confirm a concrete fix: when a SIGKILL is issued, the kernel now (1) marks the worker as killed to prevent new virtqueue usage and new flush operations, (2) fixes the virtqueue-to-worker mapping to stop...
