Vulnerability from github – Published: 2022-05-14 01:33 – Updated: 2022-05-14 01:33
VLAI
Details

An issue was discovered in Bento4 1.5.1-628. A NULL pointer dereference occurs in the function AP4_List:Find located in Core/Ap4List.h when called from Core/Ap4Movie.cpp. It can be triggered by sending a crafted file to the mp4dump binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.

GHSA-QH3P-3V24-8CRJ

Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2026-07-14 15:31
VLAI
Details

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

Input: mtk-pmic-keys - fix possible null pointer dereference

In mtk_pmic_keys_probe, the regs parameter is only set if the button is parsed in the device tree. However, on hardware where the button is left floating, that node will most likely be removed not to enable that input. In that case the code will try to dereference a null pointer.

Let's use the regs struct instead as it is defined for all supported platforms. Note that it is ok setting the key reg even if that latter is disabled as the interrupt won't be enabled anyway.

5.5 (Medium)

GHSA-QHM8-R99P-V4H8

Vulnerability from github – Published: 2024-08-17 12:30 – Updated: 2026-03-25 12:30
VLAI
Details

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

nfs: pass explicit offset/count to trace events

nfs_folio_length is unsafe to use without having the folio locked and a check for a NULL ->f_mapping that protects against truncations and can lead to kernel crashes. E.g. when running xfstests generic/065 with all nfs trace points enabled.

Follow the model of the XFS trace points and pass in an explіcit offset and length. This has the additional benefit that these values can be more accurate as some of the users touch partial folio ranges.

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.
