CVE-2026-72388 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
