In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix use-after-free in iscsitdecconnusagecount() In iscsitdecconnusagecount(), the function calls complete() while holding the conn->connusagelock. As soon as complete() is invoked, the waiter (such as iscsitcloseconnection()) may wake up and proceed to free the iscsitconn structure. If the waiter frees the memory before the current thread reaches spinunlock_bh(), it results in a KASAN slab-use-after-free as the function attempts to release a lock within the already-freed connection structure. Fix this by releasing the spinlock before calling complete().
