kernel: drm/amdgpu: zero-initialize GART table on allocation

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. When allocating a Graphics Address Remapping Table GART, the memory was not properly initialized. This could allow a local attacker to potentially access uninitialized memory, leading to information disclosure or unexpected system...

CVE-2026-53374

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: zero-initialize GART table on allocation GART TLB is flushed after unmapping but not after mapping. Since amdgpubocreatekernel does not zero-initialize the buffer, when a single PTE is written the TLB may speculativel...

CVE-2026-53374

The CVE-2026-53374 issue affects the Linux kernel’s DRM/AMDGPU path: during amdgpu_bo_create_kernel() allocation, the GART table is not zero-initialized, so writing a single PTE can cause the TLB to speculatively load other uninitialized entries from the same cacheline. This can yield stale or ga...
