Descriptions
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.
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.
A use-after-free flaw was found in kv_parse_power_table in drivers/amd/pm in the Linux kernel. When ps equals NULL, kv_parse_power_table frees adev->pm.dpm.ps. The adev->pm.dpm.ps is used in the loop of kv_dpm_fini after its first free in kv_parse_power_table, causing a use-after-free problem.
