CVE-2026-127101Sssd: sssd: null pointer dereference in pam responder when protocol version negotiation is skipped

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8 Publicada: (hace 1 hora)

Descripción

A flaw was found in SSSD's PAM responder. A local attacker can send an authentication request without first negotiating the client protocol version. The responder dereferences a NULL protocol-version pointer and crashes, disrupting SSSD-backed authentication. Repeated crafted requests can sustain the denial of service.

Debilidad (CWE): CWE-476

Datos: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Se publican tal como los indican las fuentes, en inglés.
