Linux Kernel Vulnerability in AMDGPU Graphics Driver

CVE-2024-46896

Summary

A vulnerability in the AMDGPU graphics driver within the Linux kernel could lead to unexpected behavior due to improper handling of scheduling jobs. Specifically, during job initialization, an incorrect memory access can occur, resulting in system crashes when attempting to free invalid job references after a command submission fails. This issue arises when there's an increment in the job's instruction buffer count without proper validation, compromising system stability and reliability. A recent fix addresses this by ensuring a NULL pointer is passed during the cleanup process, preventing access to invalid memory and enhancing driver performance.
