CVE-2026-76992
The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit.
Impact

An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a denial-of-service condition thus leading to a total loss of availablity.
