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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
