Detailsinfo

A vulnerability was found in Linux Kernel up to 6.4.3. It has been classified as problematic. Affected is the function offset_in_bo of the component amdgpu. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality. CVE summarizes:

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

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2023-53819 since 12/09/2025. There are known technical details, but no exploit is available.
