CVE-2019-11555

wpa: CVE-2019-11555

Severity: Medium · CVSS 5.3CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Published: Apr 18, 2019, 12:00:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 3.25% · Oct 25, 2026

The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to a NULL pointer dereference (denial of service). This affects eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c.
