CVE-2026-99106 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: free the userptr ranges when a CS fails after parser_bos
amdgpu_cs_parser_bos() allocates an HMM range for every userptr entry of
the BO list and looks up the user pages. Those ranges are only freed when
amdgpu_cs_parser_bos() itself fails or when amdgpu_cs_submit() checks
them under the notifier lock. If amdgpu_cs_patch_jobs(),
amdgpu_cs_vm_handling(), amdgpu_cs_sync_rings() or the early part of
amdgpu_cs_submit()
