Race Condition in Linux Kernel's DRM v3d Component Affecting Raspberry Pi Products

CVE-2025-21688

Summary

A race condition exists in the DRM v3d component of the Linux kernel, where the job pointer is assigned NULL post-job completion. This can lead to a NULL pointer dereference if the IRQ execution thread signals the fence just as a new job starts executing, potentially causing the system to crash when the GPU interrupts. This vulnerability affects various Raspberry Pi models running the impacted Linux kernel versions.
