CVE-2026-98000

Name	CVE-2026-98000
Description	In the Linux kernel, the following vulnerability has been resolved: hwmon: Fix potential UAF in pec_store Sashiko reports: In pec_store(), a guard(mutex)(&hwdev->lock) is taken. If the chip write operation returns an error other than -EOPNOTSUPP, the code jumps to the put label, which calls put_device(hdev). If this drops the final reference, the device is freed. When the function then returns, the guard cleanup function runs and attempts to unlock the freed mutex. Use scoped_guard() instead of guard() to avoid the problem.
