Summary

CVE-2025-21989: A vulnerability in the Linux kernel affecting AMDGPU drivers on specific old GPUs, such as R9 280X, has been identified and resolved. The issue arose due to the lack of a necessary function, .is_two_pixels_per_container, in dce60_tg_funcs. This absence led to a NULL pointer dereference upon driver loading with amdgpu.dc=1. Consequently, the recent commit bd4b125eb949785c6f8a53b0494e32795421209d added the missing function to rectify the issue.
