CVE-2026-68239

CVE-2026-68239 affects the Linux kernel DRM TTM code, specifically the ttm_pool_backup path. The issue arises because ttm_pool_backup could encounter NULL or backup handle entries (ttm_backup_page_ptr_is_handle()) which were not safely guarded for set_pages_array_wb() and could be freed erroneous...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: fix indefinite fence wait during GPU reset prereset only force-completes fences of MAPPED queues. A queue in any other state e.g. mid-eviction keeps its lastfence pending; after a GPU reset that fence never...

CVE-2026-68237

CVE-2026-68237 resolves an indefinite fence wait in drm/amdgpu/userq during a GPU reset. The pre_reset path only force-completes fences of MAPPED queues, leaving fences for queues in states like mid-eviction pending; after a reset, those fences may never signal, causing eviction/suspend workers a...
