In the Linux kernel, the following vulnerability has been resolved:
wifi: nl80211: check link is beaconing for color change
When trying to do a color change, validate that the link is
beaconing first, to avoid calling the driver with an invalid
link.
A flaw was found in the Linux kernel's nl80211 wireless subsystem. A local user with network administration privileges could cause a Denial of Service (DoS) by requesting a Basic Service Set (BSS) color change on an inactive or non-beaconing wireless link. Because the interface fails to verify that the link is beaconing before proceeding, the kernel passes an invalid link state to the underlying wireless driver, which may trigger a system crash.
