CVE-2022-49023

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix buffer overflow in elem comparison For vendor elements, the code here assumes that 5 octets are present without checking. Since the element itself is already checked to fit, we only need to check the length.
