Description OSIDB Bzimport 2025-12-09 01:04:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

amdgpu: validate offset_in_bo of drm_amdgpu_gem_va

This is motivated by OOB access in amdgpu_vm_update_range when
offset_in_bo+map_size overflows.

v2: keep the validations in amdgpu_vm_bo_map
v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map
    rather than to amdgpu_gem_va_ioctl
