Description
A flaw was found in gpsd. The hnd_129540 function, responsible for handling NMEA2000 PGN 129540 (GNSS Satellites in View) packets, fails to properly validate the user-supplied satellite count. A remote attacker can exploit this by sending a specially crafted packet with an excessive satellite count, leading to a heap-based out-of-bounds write. This memory corruption can result in a Denial of Service (DoS) and potentially allow for arbitrary code execution.
