Linux Kernel V3D GPU Interrupt Handling Vulnerability Leading to NULL Pointer Dereference

Vulnerability

A vulnerability in the Linux kernel's V3D graphics driver allows interrupts to be triggered during a GPU reset. This can cause the GPU to hang and result in a NULL pointer dereference in an interrupt context, leading to a kernel panic. The issue has been observed in the Raspberry Pi 4 Model B, running a Debian-based kernel version 6.12.25.

Impact

Exploitation of this vulnerability causes a kernel panic, disrupting system operations and potentially leading to a denial of service.
