CVE-2026-84015

Summary

A heap-based buffer overflow in PPP EAP-TLS allows remote attackers to execute arbitrary code with high privileges. This vulnerability is particularly dangerous because it can be exploited over the network without authentication, making it a critical threat to network infrastructure.

Exploitability

Exploitation is relatively straightforward as it requires only network access to trigger the buffer overflow, with no authentication needed for the initial exploit attempt.

Blast radius

If exploited, this vulnerability could compromise entire network access points and potentially allow attackers to gain full control over remote access infrastructure, affecting multiple connected systems.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

No fixed version is published. Disable EAP-TLS functionality or restrict network access to PPP endpoints until a patch is available.
