This vulnerability is a buffer over-read (CWE-126) in Qualcomm Snapdragon devices triggered by processing a malformed Fast Transition response frame with an invalid header during wireless roaming. The flaw leads to a transient denial of service condition. It affects numerous Snapdragon platforms and related wireless connectivity products. The CVSS 3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability. No vendor advisory or patch information is currently available.

The vulnerability can cause a transient denial of service (DoS) by causing the affected device to improperly handle malformed Fast Transition response frames during wireless roaming. There is no impact on confidentiality or integrity reported. The DoS is temporary and triggered by network traffic crafted to exploit the invalid header structure in the Fast Transition response frame.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, monitoring for unusual wireless roaming behavior and avoiding exposure to untrusted wireless networks may reduce risk. No official mitigation or workaround has been published by Qualcomm at this time.
