CVE-2022-23088 Information

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.
