What is CVE-2026-1940?

An incomplete fix for a previous vulnerability in GStreamer has led to a scenario where an out-of-bounds read can occur. The fix implemented did not sufficiently account for the correct byte rounding during offset calculations when parsing audio file metadata. This oversight can potentially allow malicious inputs to cause unintended memory access, leading to unpredictable behavior or security risks within applications utilizing the GStreamer framework.
