CVE-2026-46470: CWE-369 Divide By Zero in GStreamer Good Plug-ins
CVE-2026-46470 is a medium severity vulnerability in the GStreamer gst-plugins-good package prior to version 1. 28. 2. The issue occurs in the isomp4 plugin's qtdemux_audio_caps function, which insufficiently validates MP4 atom data before performing division operations. This can lead to an integer division by zero, causing a denial of service condition. There are no known exploits in the wild, and no official patch or remediation has been confirmed yet.
AI Analysis
Technical Summary
This vulnerability involves a divide-by-zero error (CWE-369) in the qtdemux_audio_caps function of the isomp4 plugin within GStreamer's gst-plugins-good before version 1.28.2. When parsing MP4 audio tracks, the plugin does not properly validate atom data prior to division, which can trigger a denial of service by crashing or halting the affected process. The CVSS 3.1 base score is 4.0, reflecting a low complexity local attack vector with no impact on confidentiality or integrity, but causing availability disruption.
Potential Impact
Successful exploitation results in a denial of service due to an integer division by zero error during MP4 audio track parsing. There is no impact on confidentiality or integrity. The attack requires local access and no privileges, but the overall severity is medium due to the availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider avoiding processing untrusted MP4 audio tracks with vulnerable versions of gst-plugins-good. Monitor official GStreamer channels for updates and apply patches promptly once available.
