A use-after-free vulnerability in the Linux kernel's hwmon pwm-fan driver was addressed by ensuring the RPM timer is stopped before freeing tachometer data. The issue involved the timer potentially accessing freed memory during driver detach, causing kernel memory errors detected by KASAN. The fix reorders resource cleanup to retire the timer before releasing its backing data, preventing invalid memory access.
