CVE-2026-53374 drm/amdgpu: zero-initialize GART table on allocation

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...
