Detailed vulnerability description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the vega10_find_dpm_states_clocks_in_dpm_table(), vega10_generate_dpm_level_enable_mask(), vega10_check_states_equal(), vega10_set_sclk_od(), vega10_set_mclk_od(), vega10_odn_update_power_state() and vega10_get_performance_level() functions in drivers/gpu/drm/amd/pm/powerplay/hwmgr/vega10_hwmgr.c. A local user can perform a denial of service (DoS) attack.
