What is CVE-2015-4146?

The EAP-pwd peer implementation in both wpa_supplicant and hostapd versions 1.0 through 2.4 harbors a vulnerability that occurs due to improper handling of Length (L) and More (M) flags. This flaw potentially allows remote attackers to exploit the system through crafted messages, leading to a denial of service condition by crashing the software, thereby disrupting network services and affecting all dependent systems.
