CVE-2022-49971

Estado: AnalizadaMedia (5.5)—

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

drm/amd/pm: Fix a potential gpu_metrics_table memory leak

Memory is allocated for gpu_metrics_table in smu_v13_0_4_init_smc_tables(), but not freed in smu_v13_0_4_fini_smc_tables(). This may cause memory leaks, fix it.
