Vulnerability from github – Published: 2024-02-23 15:30 – Updated: 2025-11-03 21:31

Details

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

mlxsw: spectrum_acl_tcam: Fix NULL pointer dereference in error path

When calling mlxsw_sp_acl_tcam_region_destroy() from an error path after failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region->group->tcam' [1].

Fix by retrieving the 'tcam' pointer using mlxsw_sp_acl_to_tcam().

Summary
MaterialX Null Pointer Dereference in getShaderNodes due to Unchecked nodeGraph->getOutput return
Details

Summary

When parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files.

Details

In src/MaterialXCore/Material.cpp, in function getShaderNodes, the following code fetches the output nodes for a given nodegraph input node:

// SNIP...
        else if (input->hasNodeGraphString())
        {
            // Check upstream nodegraph connected to the input.
            // If no explicit output name given then scan all outputs on the nodegraph.
            ElementPtr parent = materialNode->getParent();
            NodeGraphPtr nodeGraph = parent->getChildOfType<NodeGraph>(input->getNodeGraphString());
            if (!nodeGraph)
            {
                continue;
            }
            vector<OutputPtr> outputs;
            if (input->hasOutputString())
            {
                outputs.push_back(nodeGraph->getOutput(input->getOutputString())); // <--- null ptr is returned
            }
            else
            {
                outputs = nodeGraph->getOutputs();
            }
            for (OutputPtr output : outputs)
            {
                NodePtr upstreamNode = output->getConnectedNode(); // <--- CRASHES HERE
                if (upstreamNode && !shaderNodeSet.count(upstreamNode))
                {
                    if (!target.empty() && !upstreamNode->getNodeDef(target))
                    {
                        continue;
                    }
                    shaderNodeVec.push_back(upstreamNode);
                    shaderNodeSet.insert(upstreamNode);
                }
            }
        }
    }
// SNIP...

The issues arise because the nodeGraph->getOutput(input->getOutputString()) call can return a null pointer, therefore when trying to call output->getConnectedNode(), this results in a crash .

PoC

Please download nullptr_getshadernodes.mltx from the following link:

https://github.com/ShielderSec/poc/tree/main/CVE-2025-53010

build/bin/MaterialXView --material nullptr_getshadernodes.mtlx

Impact

An attacker could intentionally crash a target program that uses OpenEXR by sending a malicious MTLX file.

Vulnerability from github – Published: 2026-04-22 15:31 – Updated: 2026-05-20 00:31
VLAI
Details

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

netfs: Fix kernel BUG in netfs_limit_iter() for ITER_KVEC iterators

When a process crashes and the kernel writes a core dump to a 9P filesystem, __kernel_write() creates an ITER_KVEC iterator. This iterator reaches netfs_limit_iter() via netfs_unbuffered_write(), which only handles ITER_FOLIOQ, ITER_BVEC and ITER_XARRAY iterator types, hitting the BUG() for any other type.

Fix this by adding netfs_limit_kvec() following the same pattern as netfs_limit_bvec(), since both kvec and bvec are simple segment arrays with pointer and length fields. Dispatch it from netfs_limit_iter() when the iterator type is ITER_KVEC.

Vulnerability from github – Published: 2022-05-24 17:42 – Updated: 2023-07-28 21:30
VLAI
Details

A NULL pointer dereference flaw in kernel versions prior to 5.11 may be seen if sco_sock_getsockopt function in net/bluetooth/sco.c do not have a sanity check for a socket connection, when using BT_SNDMTU/BT_RCVMTU for SCO sockets. This could allow a local attacker with a special user privilege to crash the system (DOS) or leak kernel internal information.

GHSA-3M82-8CM9-HCF4

Vulnerability from github – Published: 2025-09-17 15:30 – Updated: 2025-12-11 21:31
VLAI
Details

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

regulator: da9063: better fix null deref with partial DT

Two versions of the original patch were sent but V1 was merged instead of V2 due to a mistake.

So update to V2.

The advantage of V2 is that it completely avoids dereferencing the pointer, even just to take the address, which may fix problems with some compilers. Both versions work on my gcc 9.4 but use the safer one.

Severity
5.5 (Medium)

Details

When the webdriver for the Browser object downloads data from a HTTP server, the data pointer is set to NULL and is allocated only in curl_write_cb when receiving data. If the server's response is an empty document, then wd->data in the code below will remain NULL and an attempt to read from it will result in a crash.

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.
