CVE-2022-49023

影响性分析说明：
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.
