What is CVE-2025-68757?

A vulnerability has been identified in the Linux kernel related to the graphics driver component. Specifically, a timer that manages the expiration of the vgem fence can lead to a potential deadlock situation when released improperly. This occurs during the handling of the dma_fence, particularly when the release function is invoked under interrupt context without adequate safeguards. The imposed risk stems from the inconsistency in lock states, which can compromise system stability, as demonstrated in related Intel DRM tests.
