RCE in FreeBSD WiFi Client: 802.11s Mesh ID Length Validation (CVE-22-23088)
CVE-2022-23088 Published on February 15, 2024

802.11 heap buffer overflow
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.
