CVE-2026-93139 in Linux
Zusammenfassung
von MITRE • 18.09.2026
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC
The loop iterated only AMDGPU_MAX_MES_PIPES times, leaving entries uninitialized for multi-XCC GPUs. This causes null pointer dereferences when accessing arrays indexed by XCC ID >= 2. Extend the loop to cover all XCCs (AMDGPU_MAX_MES_PIPES * num_xcc), matching other per-XCC arrays.
