The vulnerability allows a local user to cause denial of service conditions.
The vulnerability exists due to an error within sys/kern/uipc_usrreq.c file when calling the connect system call on a particular file descriptor with specific arguments. A local user can repeatedly send a specially crafted connect() system call to trigger a memory leak and consume all memory resources on the target system.
Successful exploitation of this vulnerability may allow a local user to cause denial of service (DoS).
