VuXML IDDescription
d4cc994f-b61d-11ec-9ebc-1c697aa5a594FreeBSD -- 802.11 heap buffer overflow

Problem 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.

Impact:

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.
