CVE-2026-97478

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the acrn virtual machine component. A race condition can occur between the acrn irqfd deassign() function and the eventfd EPOLLHUP wakeup, leading to the premature freeing of the hsm irqfd structure. This allows a shutdown work item to access a dangling pointer via the container of() function, potentially causing system instability or crashes.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
