CVE-2026-76685

HIGH 8.1 ALL-YEARS

Published 2026-09-15 · Last modified 2026-09-22 · hpe · NVD: Analyzed

A vulnerability exists in the proxy packet processing logic of the affected component where it improperly processes malformed or truncated input. An unauthenticated remote attacker could exploit this vulnerability by providing specially crafted input that triggers an integer overflow. Successful exploitation could result in a buffer overflow, potentially leading to remote code execution or denial-of-service.
