Description

CVE-2026-76685 is a high-severity vulnerability in the proxy packet processing logic of an unspecified component. It involves improper handling of malformed or truncated input that can trigger an integer overflow. An unauthenticated remote attacker could exploit this flaw by sending specially crafted input, potentially causing a buffer overflow. This may lead to remote code execution or denial-of-service conditions.

Technical Analysis

This vulnerability arises from the proxy packet processing logic improperly handling malformed or truncated input, leading to an integer overflow. Exploitation requires an unauthenticated remote attacker to send crafted input that triggers this overflow, which can cause a buffer overflow. The buffer overflow could allow execution of arbitrary code remotely or cause denial-of-service. The CVSS 3.1 base score is 8.1, indicating high severity, with network attack vector, high attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No affected versions or patch information are provided.

Potential Impact

Successful exploitation can result in remote code execution or denial-of-service, compromising system confidentiality, integrity, and availability. The vulnerability can be triggered remotely without authentication, but requires high attack complexity.
