CVE-2023-52469: drivers/amd/pm: fix a use-after-free in kv_parse_power_table
First published: Sun Feb 25 2024(Updated: )
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. <a href="https://git.kernel.org/stable/c/28dd788382c43b330480f57cd34cde0840896743">https://git.kernel.org/stable/c/28dd788382c43b330480f57cd34cde0840896743</a> <a href="https://git.kernel.org/stable/c/3426f059eacc33ecc676b0d66539297e1cfafd02">https://git.kernel.org/stable/c/3426f059eacc33ecc676b0d66539297e1cfafd02</a> <a href="https://git.kernel.org/stable/c/35fa2394d26e919f63600ce631e6aefc95ec2706">https://git.kernel.org/stable/c/35fa2394d26e919f63600ce631e6aefc95ec2706</a> <a href="https://git.kernel.org/stable/c/520e213a0b97b64735a13950e9371e0a5d7a5dc3">https://git.kernel.org/stable/c/520e213a0b97b64735a13950e9371e0a5d7a5dc3</a> <a href="https://git.kernel.org/stable/c/8a27d9d9fc9b5564b8904c3a77a7dea482bfa34e">https://git.kernel.org/stable/c/8a27d9d9fc9b5564b8904c3a77a7dea482bfa34e</a> <a href="https://git.kernel.org/stable/c/8b55b06e737feb2a645b0293ea27e38418876d63">https://git.kernel.org/stable/c/8b55b06e737feb2a645b0293ea27e38418876d63</a> <a href="https://git.kernel.org/stable/c/95084632a65d5c0d682a83b55935560bdcd2a1e3">https://git.kernel.org/stable/c/95084632a65d5c0d682a83b55935560bdcd2a1e3</a> <a href="https://git.kernel.org/stable/c/b6dcba02ee178282e0d28684d241e0b8462dea6a">https://git.kernel.org/stable/c/b6dcba02ee178282e0d28684d241e0b8462dea6a</a>
