CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's DRM subsystem, specifically related to the handling of dma_fence objects, which can be accessed in hardirq contexts. This oversight may lead to potential race conditions or deadlocks when acquiring the fence lock, impacting system stability and security. Linux kernel maintainers and developers working on graphics drivers should prioritize addressing this issue to ensure robust and secure operation of affected systems.
Original NVD Description
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.
