CVE-2026-53374

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In the AMD GPU driver, the GART (Graphics Address Remapping Table) table is not zero-initialized during allocation in the amdgpu bo create kernel() function. Because the GART TLB (Translation Lookaside Buffer) is not flushed after mapping, the TLB may speculatively load uninitialized entries from the same cacheline when a single PTE (Page Table Entry) is written. These garbage entries may appear valid, potentially causing the GPU to use a stale garbage PTE from the TLB after a subsequent write to another PTE in the same cacheline.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
