  - gpsd through release-3.27.5, fixed at commit 4c06658, contains a command injection vulnerability in
    gpsprof that allows attackers who control the GPS device subtype value to execute arbitrary shell commands
    by embedding backtick payloads in the gnuplot plot title without proper escaping. The subtype field
    sourced from a DEVICES JSON log entry or NMEA PGRMT sentence is written into a generated gnuplot program
    via a set title statement with only double-quote characters escaped, enabling arbitrary shell command
    execution as the user running gnuplot when the victim renders the generated plot through the gpsprof and
    gnuplot workflow. (CVE-2026-58459)
