Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: drop redundant sched job cleanup when cs is aborted Once command submission failed due to userptr invalidation in amdgpu_cs_submit, legacy code will perform cleanup of scheduler job. However, it's not needed at all, as former commit has integrated job cleanup stuff into amdgpu_job_free. Otherwise, because of double free, a NULL pointer dereference will occur in such scenario.

Executive Summary

This vulnerability occurs in the Linux kernel's amdgpu driver where redundant cleanup of scheduler jobs happens when a command submission fails due to user pointer invalidation. The legacy code performs an unnecessary cleanup that has already been handled elsewhere, leading to a double free and resulting in a NULL pointer dereference.

Impact Analysis

The vulnerability can cause a NULL pointer dereference in the Linux kernel, which may lead to system crashes or instability when the affected code path is triggered.
