CVE-2026-72388Source published Source updated
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. This vulnerability arises from the incorrect acquisition of fence locks, where an IRQ-safe variant was not consistently used for `dma_fence` objects. Since these objects can be accessed from hard interrupt (hardirq) context by other drivers, this improper locking could lead to race conditions. Such conditions may result in system instability or a denial of service. Red Hat severity: Moderate —…
