Summary

CVE-2022-23303

The implementations of SAE in hostapd
are vulnerable to side channel attacks as a result of
cache access patterns.

CVE-2022-23304

The implementations of EAP-pwd are vulnerable
to side-channel attacks as a result of cache access patterns.

CVE-2022-37660

The PKEX code remains active even after
a successful PKEX association. An attacker that successfully
bootstrapped public keys with another entity using PKEX in
the past, will be able to subvert a future bootstrapping
by passively observing public keys.

For Debian 11 bullseye, these problems have been fixed in version
2:2.9.0-21+deb11u3.

We recommend that you upgrade your wpa packages.

For the detailed security status of wpa please refer to
its security tracker page at:
