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.

CVE-2022-49023 [HIGH] CWE-120 kernel: wifi: cfg80211: fix buffer overflow in elem comparison
kernel: wifi: cfg80211: fix buffer overflow in elem comparison
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.
A buffer overflow vulnerability was found in the Linux kernel. When performing an elem comparison, no length checking is performed, which can result in the system's loss of availability.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
