A heap-based buffer overflow in GStreamer's rtpL16depay element occurs while processing RTP payload data. A remote attacker who can get that library path to handle a crafted RTP payload can run arbitrary code as the current process. Who is reachable depends on how an application uses the element; no affected versions are listed.
What to do: Apply GStreamer's update for CVE-2026-111183 when published; no fixed version or workaround is stated.

Description · NVD
GStreamer rtpL16depay Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the processing of RTP payload elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-31143.
