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. (NVD)
