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

Description The issue is related to a race condition in the Linux kernel's drm/lima component. This race condition can occur when a rendering job takes long enough to trigger the drm sched job timeout handler but still completes before the hard reset is done by the timeout handler. In some cases, this can result in a refcount imbalance on lima pm idle. The problem can be prevented by masking the irqs at the beginning of the timeout handler.

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