{"id":"ALSA-2026:0770","summary":"Important: gpsd security update","details":"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.  \n\nSecurity Fix(es):  \n\n  * gpsd: gpsd: Denial of Service due to malformed NAVCOM packet parsing (CVE-2025-67269)\n  * gpsd: gpsd: Arbitrary code execution via heap-based out-of-bounds write in NMEA2000 packet handling (CVE-2025-67268)\n\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n","modified":"2026-02-04T02:17:23.214738Z","published":"2026-01-19T00:00:00Z","related":["CVE-2025-67268","CVE-2025-67269"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:0770"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-67268"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2025-67269"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2426810"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2426835"},{"type":"ADVISORY","url":"https://errata.almalinux.org/10/ALSA-2026-0770.html"}],"affected":[{"package":{"name":"gpsd","ecosystem":"AlmaLinux:10","purl":"pkg:rpm/almalinux/gpsd"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:3.26.1-1.el10_1.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux10/ALSA-2026:0770.json"}},{"package":{"name":"gpsd-clients","ecosystem":"AlmaLinux:10","purl":"pkg:rpm/almalinux/gpsd-clients"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:3.26.1-1.el10_1.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux10/ALSA-2026:0770.json"}},{"package":{"name":"python3-gpsd","ecosystem":"AlmaLinux:10","purl":"pkg:rpm/almalinux/python3-gpsd"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:3.26.1-1.el10_1.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux10/ALSA-2026:0770.json"}}],"schema_version":"1.7.3"}
