CVE-2026-121390

Name	CVE-2026-121390
Description	FreeRDP 3.0.0 before 3.32.2 built with WITH_AAD=ON contains a reachable assertion because its ARM gateway response parser accepts a missing or non-string redirectedServerCert field and passes a null buffer to the certificate parser. A malicious or malformed user-selected gateway can return such a response to abort the client process.
Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
