CVE-2026-72300

Service interruption via truncated vendor-array header

Published Aug 15, 2026 · Updated Aug 15, 2026

Out-of-bounds read in Linux kernel ASoC SOF topology parsing allows local users to interrupt service via malformed private data. sof_parse_token_sets() reads array->size before confirming that the remaining data contains a complete snd_soc_tplg_vendor_array header, and a signedness error also permits negative or too-small declared sizes. Low-privileged local access and the ability to supply malformed SOF topology data are required; the published impact is limited to availability.
