CVE-2011-2480
https://notcve.org/view.php?id=CVE-2011-2480
27 Nov 2019 — 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.

A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.
