State: Published
Severity: 9.8 Critical
Published: Feb 15, 2024
Updated: Apr 24, 2025
Reserved: Jan 10, 2022

Description

The 802.11 beacon handling routine failed to validate the length of an IEEE 802.11s Mesh ID before copying it to a heap-allocated buffer.

While a FreeBSD Wi-Fi client is in scanning mode (i.e., not associated with a SSID) a malicious beacon frame may overwrite kernel memory, leading to remote code execution.
