No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.
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.
CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).
No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.
Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
