CVE-2026-4747 Remote code execution via RPCSEC_GSS packet validation

Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow. Notably, this does not...

CVE-2026-4747

CVE-2026-4747 is a FreeBSD vulnerability in the RPCSEC_GSS implementation (kgssapi.ko) where svc_rpc_gss_validate() copies attacker-controlled data into a 128-byte stack buffer without enforcing size, enabling a 304-byte overflow when credential bodies up to 400 bytes are supplied. This can lead ...
