CVE-2025-47807Public exploit

Application crash via unchecked regex replacement result

Published Aug 7, 2025 · Updated Aug 12, 2025

NULL-pointer dereference in GStreamer gst-plugins-base before 1.26.2 allows attackers to crash applications via crafted SubRip subtitles. The subparse plugin's subrip_unescape_formatting function passes a NULL result from g_regex_replace to strcpy without checking it. Exploitation requires an application to parse a crafted subtitle file, and the resulting impact is an application crash.
