CVE-2026-43305

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

Description A mismatched unlock for the DMUB HW lock in the HWSS fast path occurs in the Linux kernel. This happens because the evaluation for whether the DMUB HW lock is required differs from the evaluation for whether it needs to be unlocked, which can lead to a system hang when the fast path is used for ASICs without FAMS support.

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