CVE-2026-23295

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

Description A deadlock situation can occur in the Linux kernel’s accel/amdxdna component during suspend and resume operations. This happens when an application sends a query IOCTL while the system is in auto suspend mode. The query path acquires dev lock and then calls pm runtime resume and get(), which waits for the suspend process to finish. Simultaneously, the suspend callback tries to obtain dev lock, leading to a deadlock. The issue is resolved by releasing dev lock before calling pm runtime resume and get() and reacquiring it afterward, as well as acquiring dev lock in the resume callback to maintain consistent locking.

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