A use-after-free vulnerability in the Linux kernel's hardware monitoring (hwmon) subsystem, specifically in the powerz driver, was fixed. The issue occurs when the powerz_disconnect() function frees a USB Request Block (URB) and releases a mutex, but a subsequent powerz_read() call can access the freed URB pointer, leading to a use-after-free condition. The fix involves setting the URB pointer to NULL upon disconnect and adding checks to prevent dereferencing freed memory. This vulnerability has a CVSS score of 7.8 and affects multiple Linux kernel versions prior to 6.8.0-1064.72 and related versions. A patch is available and should be applied to mitigate the risk.
