CVE-2026-19387 is a heap out-of-bounds write in the adpcmdec element of GStreamer's gst-plugins-bad package during IMA/DVI ADPCM audio decoding. Insufficient validation of per-block sample counts in multi-channel streams allows a specially crafted WAV file to trigger writes beyond the allocated output buffer. Processing the malicious media can cause application crashes, denial of service, memory corruption, or potentially arbitrary code execution.
