Every event links to its source. Catalog dates are each catalog's own; day offsets count from NVD publication. Data: JSON
Insufficient validation of the per-block sample count in the IMA/DVI ADPCM decoder (adpcmdec element, gst-plugins-bad) allows a crafted multi-channel WAV file to write beyond the allocated output buffer. Outcome ranges from application crash to memory corruption; Red Hat lists arbitrary code execution as a potential worst case.
Patch: update gst-plugins-bad from your distribution’s package repository. Red Hat advisory: CVE-2026-19387.
