{"id":"DEBIAN-CVE-2025-21989","details":"In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: fix missing .is_two_pixels_per_container  Starting from 6.11, AMDGPU driver, while being loaded with amdgpu.dc=1, due to lack of .is_two_pixels_per_container function in dce60_tg_funcs, causes a NULL pointer dereference on PCs with old GPUs, such as R9 280X.  So this fix adds missing .is_two_pixels_per_container to dce60_tg_funcs.
