Detailed vulnerability description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the rt2x00mac_bss_info_changed() function in drivers/net/wireless/ralink/rt2x00/rt2x00mac.c, within the rt2x00lib_disable_radio(), rt2x00lib_start() and rt2x00lib_stop() functions in drivers/net/wireless/ralink/rt2x00/rt2x00dev.c. A local user can perform a denial of service (DoS) attack.
