CVE-2023-52469

In the Linux kernel, the following vulnerability has been resolved: drivers/amd/pm: fix a use-after-free in kv_parse_power_table When ps allocated by kzalloc equals to NULL, kv_parse_power_table frees adev->pm.dpm.ps that allocated before. However, after the control flow goes through the following call chains: kv_parse_power_table |-> kv_dpm_init |-> kv_dpm_sw_init |-> kv_dpm_fini The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its first free in kv_parse_power_table and causes a use-after-free bug.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/amd/pm: corrige un use-after-free en kv_parse_power_table Cuando ps asignado por kzalloc es igual a NULL, kv_parse_power_table libera adev->pm.dpm.ps que se asignó antes. Sin embargo, después de que el flujo de control pasa por las siguientes cadenas de llamadas: kv_parse_power_table |-> kv_dpm_init |-> kv_dpm_sw_init |-> kv_dpm_fini El adev->pm.dpm.ps se usa en el bucle for de kv_dpm_fini después de su primera liberación en kv_parse_power_table y provoca un error de use-after-free.
