Title
PX4 Autopilot through 1.17.0 NULL Pointer Dereference via sd_stress
Summary
PX4 Autopilot through 1.17.0 contains a NULL pointer dereference vulnerability in the sd_stress command where the -b byte count parameter is parsed without validation before being passed to malloc() and memset(). Attackers with shell access, including through MAVLink, can supply invalid byte count values to crash the flight controller.

CVE-2026-102623 (GCVE-0-2026-102623)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:06 – Updated: 2026-09-29 19:51

Title
Kubevirt: kubevirt: virt-controller nil-pointer dereference via malformed ephemeral volume
Summary
A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment.
Severity

Title
WinFsp through 2.2.26215 NULL Pointer Dereference via Fast I/O
Summary
WinFsp through 2.2.26215 contains a null pointer dereference vulnerability in the kernel driver's Fast I/O device control handler that fails to validate the volume context before use. An unprivileged local user can trigger a denial of service by opening the WinFsp control device and issuing FSP_IOCTL_TRANSACT requests, causing a system crash.

CVE-2026-93588 (GCVE-0-2026-93588)

Title
ImageMagick before 7.1.2-31 Null Pointer Dereference via PNM
Summary
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.

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.
