Description
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.
