Description OSIDB Bzimport 2026-09-24 17:06:36 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: nl80211: reject beacons with bad HE operation

The HE operation element not only needs to be longer than
the fixed part, but also have an appropriate size for the
variable part inside of it. Check this.
