How to fix?

Upgrade Debian:12 linux-6.12 to version 6.12.113-1~deb12u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: don't allow injecting frames wider than the chanctx

Frames injected on a monitor interface can carry a radiotap field requesting a bandwidth, which mac80211 passes down to the driver regardless of the the actual operational bandwidth.

If the bandwidth requested is too wide, that triggers a warning in hwsim:

WARN_ON(hwsim_get_chanwidth(bw) > hwsim_get_chanwidth(confbw))

Drop such frames entirely instead since they cannot be sent.
