CVE-2023-53819

Linux

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
