Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ieee80211_radiotap_iterator_init function in net/wireless/radiotap.c in the Linux kernel before 3.11.7 does not check whether a frame contains any data outside of the header, which might allow attackers to cause a denial of service (buffer over-read) via a crafted header.
