Published: Translated: NVD NIST

Summary

A stack-based buffer overflow in the firmware of Broadcom Wi-Fi HardMAC SoC chips occurs when the firmware supports CCKM Fast and Secure Roaming and the feature is enabled in RAM. This allows remote attackers to execute arbitrary code via a crafted reassociation response frame with a Cisco IE (156).

Risk Assessment

Attackers can remotely take control of the device, potentially leading to serious security breaches within the network. This impacts the integrity and confidentiality of data transmitted by devices using the vulnerable software.

Recommendation

It is recommended to update the firmware to the latest version that addresses this vulnerability. Consider disabling the CCKM Fast and Secure Roaming feature if it is not necessary.
