Description OSIDB Bzimport 2025-07-10 08:03:29 UTC 
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.
