FreeBSD -- File description reference count leak

Problem Description: If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file...

FreeBSD -- Reference count overflow in mqueue filesystem

Problem Description: System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file. Impact: A local user can use this flaw to obtain access...
