The cfg80211_wext_giwessid function in net/wireless/wext-compat.c in the
Linux kernel before 2.6.36-rc3-next-20100831 does not properly initialize
certain structure members, which allows local users to leverage an
off-by-one error in the ioctl_standard_iw_point function in
net/wireless/wext-core.c, and obtain potentially sensitive information from
kernel heap memory, via vectors involving an SIOCGIWESSID ioctl call that
specifies a large buffer size.
