Red Hat Security Advisory: gpsd security update
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) For 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.
AI Analysis
Technical Summary
Gpsd mediates access to GPS sensors connected via serial or USB interfaces, allowing multiple clients to query location and movement data. Two vulnerabilities have been fixed: a denial of service caused by malformed NAVCOM packet parsing (CVE-2025-67269) and arbitrary code execution due to a heap-based out-of-bounds write in NMEA2000 packet handling (CVE-2025-67268). These vulnerabilities affect Red Hat Enterprise Linux 10 versions of gpsd. Red Hat Product Security has issued an advisory (RHSA-2026:0770) and provided updated packages to remediate these issues.
Potential Impact
Successful exploitation of CVE-2025-67269 can cause denial of service by crashing the gpsd service. CVE-2025-67268 is more severe, allowing an attacker to execute arbitrary code on the host system via a heap-based out-of-bounds write. This could lead to full system compromise if exploited. Both vulnerabilities affect gpsd running on Red Hat Enterprise Linux 10 on various architectures including x86_64, s390x, ppc64le, and aarch64.
Mitigation Recommendations
Red Hat has released updated gpsd packages for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2026:0770 and the referenced article https://access.redhat.com/articles/11258. Applying this official fix will mitigate the risk of denial of service and arbitrary code execution via the described vulnerabilities.
