CVE-2026-56789 RTKLIB 2.4.3 - Heap Buffer Overflow and Stack Read via Oversized RINEX Epoch Satellite Count

RTKLIB through 2.4.3 contains a heap buffer overflow vulnerability in the readrnxobsb function in src/rinex.c that allows attackers to trigger memory corruption by failing to clamp satellite count values from RINEX epoch headers. Attackers can craft malicious RINEX files declaring more than 64...

gpsd: gpsd: Arbitrary code execution via heap-based out-of-bounds write in NMEA2000 packet handling

A flaw was found in gpsd. The hnd129540 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,...
