A fix has been implemented and merged into the Linux kernel. Users and administrators should update to the fixed kernel version to remediate this vulnerability. No additional mitigation steps are indicated.
Description
A use-after-free vulnerability was identified and fixed in the Linux kernel's hp-wmi-sensors hwmon driver. The issue occurs because fungible_show() reads a sensor state pointer after the lock protecting it has been released, allowing concurrent access that can lead to use-after-free. The fix involves taking the state lock around the read in fungible_show() to prevent concurrent free-and-replace operations.
