In the Linux kernel, the following vulnerability has been resolved:

drm/amd/pp: Fix potential NULL pointer dereference in atomctrl_initialize_mc_reg_table

The function atomctrl_initialize_mc_reg_table() and atomctrl_initialize_mc_reg_table_v2_2() does not check the return value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to retrieve vram_info, it returns NULL which is later dereferenced.
