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