Description OSIDB Bzimport 2024-08-26 11:21:41 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: nl80211: disallow setting special AP channel widths

Setting the AP channel width is meant for use with the normal
20/40/... MHz channel width progression, and switching around
in S1G or narrow channels isn't supported. Disallow that.
