Description
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 renoir_init_smc_tables(), but not freed in int smu_v12_0_fini_smc_tables(). Free it!
A memory leak vulnerability has been identified in the Linux kernel's handling of AMD GPU metrics. The issue arises because memory allocated for the gpu_metrics_table in the renoir_init_smc_tables() function is not properly freed in the smu_v12_0_fini_smc_tables() function, leading to a potential memory leak.
