Memory Corruption while invoking IOCTL calls when concurrent access to shared buffer occurs.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2025-47386 is a high public vulnerability record for qualcomm ar8031 firmware. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether qualcomm ar8031 firmware is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: qualcomm/ar8031 firmware; qualcomm/ar8035 firmware; qualcomm/csra6620 firmware; qualcomm/csra6640 firmware. Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: CVSS 7.8 (technical impact); EPSS 0.1% (30-day exploitation probability). It is not currently listed in the CISA Known Exploited catalog. Weakness classes: CWE-416. Sources contributing to this record: cve_org, epss, nvd. Public exploit references, when present, are outbound links only and are not proof of active exploitation.
