CVE-2026-125712

Gst-plugins-base: gst-plugins-base: missing bounds checks in rtcp sdes packet parsing

No exploitation reported by the sources we read.

  • Published2026-11-10
  • WeaknessCWE-125

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

A flaw was found in GStreamer's gst-plugins-base RTCP SDES packet parser. A remote sender able to reach an active media session can supply a malformed SDES entry whose declared length exceeds the received packet. Missing bounds validation can cause the receiver to read beyond the packet buffer, potentially crashing the application or exposing a limited amount of process memory.
