Description

This security bulletin contains information about 1 vulnerability.


1) Improper Check or Handling of Exceptional Conditions (CVE-ID: CVE-2026-46276)

CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper handling of zero-size resource initialization in amdgpu_ttm_init_on_chip() when initializing on-chip memory resources during amdgpu module loading on RDNA4 hardware. A local user can trigger initialization of the amdgpu driver on affected hardware to cause a denial of service.

The issue occurs only on RDNA4 hardware where the GDS, GWS, and OA on-chip memory resources are absent, and the crash is observed when CONFIG_DRM_DEBUG_MM is enabled.
