CVE-2025-47808: In GStreamer through 1.26.1, the subparse plugin's tmplayer_parse_line function may dereference a NULL pointer while parsing a subtitle file

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.50% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: gst-plugins-base (Alpine:v3.22) 1.26.2-r0; gst-plugins-base1.0 (Debian:11) 1.18.4-2+deb11u4; gst-plugins-base1.0 (Debian:12) 1.22.0-3+deb12u5.

Low priority for now. Upgrade to gst-plugins-base (Alpine:v3.22) 1.26.2-r0; gst-plugins-base1.0 (Debian:11) 1.18.4-2+deb11u4; gst-plugins-base1.0 (Debian:12) 1.22.0-3+deb12u5 or later.
