CVE-2026-93280

High

In the Linux kernel, the following vulnerability has been resolved: greybus: audio: bound the topology section sizes against the fetched size gb_audio_gb_get_topology() fetches a topology blob of a module-supplied size, and gbaudio_tplg_parse_data() then walks it by adding the module-supplied size_dais, size_controls and size_widgets fields to form the control, widget and route section offsets. Those le32 sizes are never checked against the fetched blob, so a module reporting a small topology size but large section sizes makes the offsets point past the allocation, and parsing reads out of bounds. Reject a topology whose section sizes do not fit within the fetched size before it is parsed.
