ALSA-2026:0770

gpsd is a service daemon that mediates access to a GPS sensor connected to the host computer by serial or USB interface, making its data on the location/course/velocity of the sensor available to be queried on TCP port 2947 of the host computer. With gpsd, multiple GPS client applications (such as navigational and war-driving software) can share access to a GPS without contention or loss of data. Also, gpsd responds to queries with a format that is substantially easier to parse than NMEA 0183.

Security Fix(es):

• gpsd: gpsd: Denial of Service due to malformed NAVCOM packet parsing (CVE-2025-67269)
• gpsd: gpsd: Arbitrary code execution via heap-based out-of-bounds write in NMEA2000 packet handling (CVE-2025-67268)
