Last modified

CVE-2015-4146 is a vulnerability of currently unknown severity. The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not clear the L (Length) and M (More) flags before determining if a response should be fragmented, which allows remote attackers to cause a denial of service (crash) via a crafted message.. EPSS estimates a 3.48% chance of exploitation in the next 30 days.
