Details

In the Linux kernel, the following vulnerability has been resolved:

fs: sysfs: Fix reference leak in sysfsbreakactive_protection()

The sysfsbreakactiveprotection() routine has an obvious reference leak in its error path. If the call to kernfsfindandget() fails then kn will be NULL, so the companion sysfsunbreakactive_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released.

Fix the leak by adding an explicit kobject_put() call when kn is NULL.
