CVE-2026-11774: Integer Overflow or Wraparound in Red Hat Red Hat Directory Server 11CVE-2026-11774 0 CVE-2026-11774 is an integer overflow vulnerability in the SASL I/O layer of Red Hat Directory Server 11 (389-ds-base). The flaw occurs in sasl_io_start_packet() when adding sizeof(uint32_t) to a crafted SASL packet length prefix causes an unsigned wraparound, bypassing size limits and leading to a heap buffer overflow. This can be exploited after a successful SASL bind with integrity protection to cause denial of service or remote code execution. In FreeIPA and Red Hat Identity Management deployments, any domain user with valid credentials can trigger this remotely.
