Vulnerability from github – Published: 2023-12-05 00:31 – Updated: 2023-12-05 00:31
VLAI
Details

The ACEManager component of ALEOS 4.16 and earlier does not adequately perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.

Severity

GHSA-MRQ3-QX26-XJXJ

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-06 18:32
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

i2c: cros-ec-tunnel: defer probe if parent EC is not present

When i2c-cros-ec-tunnel and the EC driver are built-in, the EC parent device will not be found, leading to NULL pointer dereference.

That can also be reproduced by unbinding the controller driver and then loading i2c-cros-ec-tunnel module (or binding the device).

Vulnerability from github – Published: 2026-07-15 00:31 – Updated: 2026-07-15 15:33
VLAI
Details

A null pointer dereference vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, affecting the ReadRevisionAttribute function used in multiple clusters (Channel, Account Login, TargetNavigator, etc.). The function lacks proper validation of the delegate pointer before dereferencing. A remote unauthenticated attacker can exploit this issue by sending a crafted read request, causing the device to crash (denial of service). This issue has been confirmed in SDK version v1.4 (commit ab3d5ae).

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.
