AI-suggested
1. Monitor Qualcomm and device vendor advisories for official patches addressing CVE-2025-47402 and apply them promptly once available. 2. Implement network-level filtering to detect and block malformed or oversized authentication information elements in wireless frames, reducing exposure to crafted packets. 3. Employ wireless intrusion detection/prevention systems (WIDS/WIPS) to monitor for anomalous frame patterns indicative of exploitation attempts. 4. Segment critical wireless networks and restrict access to trusted devices to minimize the attack surface. 5. For enterprise-managed mobile devices, enforce security policies that limit exposure to untrusted wireless networks. 6. Collaborate with device manufacturers to verify firmware updates include fixes for this vulnerability. 7. Conduct regular security assessments of wireless infrastructure to identify and remediate vulnerable devices. 8. Educate IT and security teams about this vulnerability to ensure rapid response to any signs of exploitation. 9. In environments where patching is delayed, consider temporary disabling or limiting wireless features that process authentication information elements if feasible. 10. Maintain updated asset inventories to identify all devices with affected Qualcomm components for targeted mitigation.
Description
Transient DOS when processing a received frame with an excessively large authentication information element.
