CWE-193

Description

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.

Affected configurations

• linux linux kernel (< 2.6.36) • linux linux kernel 2.6.36 • opensuse opensuse 11.1 • suse linux enterprise desktop 11 • suse linux enterprise real time extension 11 • suse linux enterprise server 11 • canonical ubuntu linux 6.06 • canonical ubuntu linux 8.04 • canonical ubuntu linux 9.04 • canonical ubuntu linux 9.10 • canonical ubuntu linux 10.04 • canonical ubuntu linux 10.10
