CVE-2026-72388
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Always use the IRQ-safe variant when acquiring the fence lock
Since dma_fence objects can be shared with other subsystems, they may be
accessed from hardirq context in those drivers, and we have to take
that into account by also using the IRQ-safe variant when acquiring
the lock.
While at it, switch to the guard model.
