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.

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.

A flaw has been found in Freedesktop Poppler 26.07.0. Impacted is the function JBIG2Stream::rewind of the file poppler/JBIG2Stream.cc. This manipulation causes null pointer dereference. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 26.08.0 is recommended to address this issue. Patch name: 5e49250f13b0390edeb3f90eb4c02c9941f97067. Upgrading the affected component is advised.

CVE-2026-92626 (GCVE-0-2026-92626)

Title
Control iD iDSecure Unauthenticated Denial of Service
Summary
Control iD iDSecure versions prior to 4.8.3.0 are affected by an unauthenticated Denial of Service.
The /api/dguardintegration/dguardVersion endpoint dereferences DGuard integration login state that may be unset, raising an unhandled null reference exception. The exception is thrown from an asynchronous method that returns void, so it is not observed by a caller and can terminate the iDSecure process.

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.
