In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix missing .istwopixelspercontainer
Starting from 6.11, AMDGPU driver, while being loaded with amdgpu.dc=1, due to lack of .istwopixelspercontainer function in dce60tgfuncs, causes a NULL pointer dereference on PCs with old GPUs, such as R9 280X.
So this fix adds missing .istwopixelspercontainer to dce60tgfuncs.
(cherry picked from commit bd4b125eb949785c6f8a53b0494e32795421209d)
