CVE-2026-127100Sssd: sssd: local denial of service through unchecked oauth2 json code type in pam responder

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 Veröffentlicht: (vor 29 Minuten)

Beschreibung

A flaw was found in SSSD's PAM responder on builds with the JSON PAM extension enabled. A local attacker can submit a crafted authentication request containing a non-string OAuth2 code value. Missing JSON type validation leads to a NULL pointer dereference, terminating the PAM responder and disrupting SSSD-backed authentication.

Schwachstellentyp (CWE): CWE-476

Daten: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Wiedergegeben wie in der Quelle, auf Englisch.
