CVE-2026-25075 (GCVE-0-2026-25075)

Vulnerability from cvelistv5 – Published: 2026-03-23 18:33 – Updated: 2026-07-14 15:53

Title
strongSwan 4.5.0 < 6.0.5 EAP-TTLS AVP Parsing Integer Underflow
Summary
strongSwan versions 4.5.0 prior to 6.0.5 contain an integer underflow vulnerability in the EAP-TTLS AVP parser that allows unauthenticated remote attackers to cause a denial of service by sending crafted AVP data with invalid length fields during IKEv2 authentication. Attackers can exploit the failure to validate AVP length fields before subtraction to trigger excessive memory allocation or NULL pointer dereference, crashing the charon IKE daemon.

Vulnerability from cvelistv5 – Published: 2026-06-10 03:08 – Updated: 2026-06-30 01:46
VLAI
Title
QTS, QuTS hero
Summary
A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following versions: QTS 5.2.9.3492 build 20260507 and later QuTS hero h5.2.9.3499 build 20260514 and later QuTS hero h5.3.4.3500 build 20260520 and later QuTS hero h6.0.0.3459 build 20260409 and later

Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
