Vulnerability Name:

CVE-2011-2480 (CCN-172514)

Assigned:

2011-06-20

Published:

2011-06-20

Updated:

Summary:

Information Disclosure vulnerability in the 802.11 stack, as used in FreeBSD before 8.2 and NetBSD when using certain non-x86 architectures. A signedness error in the IEEE80211_IOC_CHANINFO ioctl allows a local unprivileged user to cause the kernel to copy large amounts of kernel memory back to the user, disclosing potentially sensitive information.
