A vulnerability in the Linux kernel's AMDGPU driver was resolved by zero-initializing the GART table on allocation to prevent stale or uninitialized page table entries (PTEs) from being used by the GPU. The flaw involved speculative loading of uninitialized entries from the same cacheline, potentially causing the GPU to use stale garbage PTEs. This issue was fixed by calling memset_io() to zero-initialize the GART table immediately after allocation. The vulnerability affects certain versions of the linux-aws kernel prior to 6.8.0-1061.64~22.04.1 and related versions. A patch is available and should be applied to mitigate the risk.
