|CVSS SCORE||8.3, (AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H)|
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of FreeBSD Kernel. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of 802.11 Wi-Fi beacon frames. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the kernel.
FreeBSD has issued an update to correct this vulnerability. More details can be found at:
