Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0-rc6-01399-g941aae326315

Description The Linux kernel contains a flaw within the DRM/VC4 subsystem related to deadlock handling. Specifically, if vc4 hdmi reset link() returns -EDEADLK, indicating a deadlock in the locking context, the kernel does not properly address the situation. Instead of dropping currently held locks and waiting for the contended lock to become available, the kernel may produce warnings and potentially experience instability. This issue can occur during output polling, as evidenced by kernel logs.

Recommendations Update to version 6.1.0-rc6-01399-g941aae326315 or a later version to resolve this issue.
