CVE-2026-80641
Overview
CVE-2026-80641 is a known-severity vulnerability. It was published on August 28, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: wlcore: enable the right set of ciphers
The firmware version number check for IGTK introduced in
commit c34dbc5900b0 ("wifi: wlcore: Add support for IGTK key")
lets the amount of ciphers decrease on every boot of a too old firmware and
that is practically happening. It also does not take into account other
chips than the wl18xx. On some wl128x, the following can be observed
when connecting via nm to a common ap:
[ 484.113311] wlcore: WARNING could not set keys
[ 484.117828] wlcore: ERROR Could not add or replace key
[ 484.123016] wlan0: failed to set key (5, ff:ff:ff:ff:ff:ff) to hardware (-5)
[ 484.123046] wlcore: Hardware recovery in progress. FW ver: Rev 7.3.10.0.142
