AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions hostapd versions 2.0 through 2.5

Description The issue is related to the eap pwd process function in eap server/eap server pwd.c, which does not validate the size of the reassembly buffer for the final fragment in EAP-pwd messages. This can be exploited by remote attackers to cause a denial of service (process termination) by sending a large final fragment in an EAP-pwd message, particularly when used with an internal EAP server or a RADIUS server with EAP-pwd enabled.

Recommendations For hostapd versions 2.0 through 2.5, update to version 2.6 or later to resolve the issue.
