Title
open62541 Shared Client ua_client_connect.c responseReadNamespacesArray null pointer dereference
Summary
A vulnerability was identified in open62541 up to 1.5.5. Affected by this issue is the function responseReadNamespacesArray of the file src/client/ua_client_connect.c of the component Shared Client Library. Such manipulation of the argument Server_NamespaceArray leads to null pointer dereference. The attack can be executed remotely. The attack requires a high level of complexity. The exploitation is known to be difficult. The exploit is publicly available and might be used. The project closed the issue report, stating that this is not the official way to report a security vulnerability.

Title
GNU LibreDWG DWG File dwg.c dwg_next_entity null pointer dereference
Summary
A vulnerability was found in GNU LibreDWG up to 0.13.4. The impacted element is the function dwg_next_entity of the file src/dwg.c of the component DWG File Handler. Performing a manipulation of the argument next_obj results in null pointer dereference. The attack must be initiated from a local position. The exploit has been made public and could be used. Upgrading to version 0.14 is sufficient to resolve this issue. The patch is named dde45dac3c4d902e4d8fed150a8017b9732019c9. Upgrading the affected component is recommended. Different than CVE-2026-9503.

Title
GPAC Media File write_nhml.c nhmldump_send_frame null pointer dereference
Summary
A flaw has been found in GPAC 26.02.0. This affects the function nhmldump_send_frame of the file src/filters/write_nhml.c of the component Media File Handler. Executing a manipulation can lead to null pointer dereference. The attack requires local access. The exploit has been published and may be used. This patch is called bd1d94e70e3bef364c07c5a1d94eca5c9f56e160. A patch should be applied to remediate this issue. The project explains: "I would consider most of these more as bugs than vulns but anyway they're good to fix".

Title
RPK Server Signature Algorithm Selection Can Dereference a Missing Certificate
Summary
Issue summary: In a server or client configuration with RFC7250 Raw Public Keys (RPKs)
enabled, and only the private key (with no associated certificate) configured locally,
a NULL pointer dereference may occur when the remote peer solicits raw public keys and
also sends the typically omitted "signature_algorithms_cert" TLS extension.
Impact summary: The impact is limited to a possible Denial of Service as a result of
an application abort, no data disclosure or remote command execution are possible.
CWE: CWE-476: NULL Pointer Dereference
Description: While a passing comment in sample code in the documentation suggests
that key-only RPK configurations are supported, the best-practice RPK configuration
is to always configure a corresponding certificate (possibly self-signed or
signed by any convenient CA).
When the private key is configured along with a matching certificate, the
"signature_algorithms_cert" extension is handled reliably even without the
fix, and peer clients or servers that don't support raw public keys may be
able to complete a TLS connection by pinning or verifying the corresponding
certificate or its public key.
Deployments that prefer to configure just a private key with no certificate
need to upgrade to an updated release as noted below.
FIPS impact: no
No FIPS modules are affected by this issue, as the SSL protocol implementation
is outside the OpenSSL FIPS module boundary.

Title
NULL-pointer dereference in Zephyr OCPP CALLRESULT parsing via unchecked strtok_r/atoi
Summary
The OCPP 1.6 client in subsys/net/lib/ocpp/ocpp.c reconstructs a session handle and PDU id from the uid field of a CALLRESULT message. In ocpp_process_server_msg() the code calls atoi(strtok_r(uid, "-", &tmp)) without checking the strtok_r return value. When the server-supplied uid is empty or contains no - delimiter, strtok_r() returns NULL and atoi(NULL) dereferences a NULL pointer, which is undefined behaviour.
The uid originates from network data: parse_rpc_msg() in subsys/net/lib/ocpp/ocpp_j.c JSON-parses a frame received from the OCPP central system over TCP/WebSocket and copies the server-controlled string into the local buffer. A malicious or compromised central system, or a man-in-the-middle on a non-TLS ws:// connection, can return a malformed uid to reach the defect. No authentication beyond the existing server connection (or MITM position) is required, and the reconstructed pointer is membership-validated by ocpp_session_is_valid(), so the impact is limited to the NULL dereference rather than arbitrary pointer use.
On Zephyr targets that trap access to address 0 (MMU/MPU platforms or CONFIG_NULL_POINTER_EXCEPTION_DETECTION), the dereference faults inside the OCPP reader thread and invokes the fatal handler, producing a remote denial of service of the charge point; on bare targets where address 0 is readable the call returns 0 and is benign, so the impact is availability-only and platform-conditional.
The applied fix guards only the first atoi(); the second strtok_r(NULL, "-", &tmp) followed by pdu = atoi(buf) in the same function remains unguarded and the identical NULL dereference is still reachable from the same network input when the uid has a first token but no second --delimited token. A complete fix should validate the second token as well.

Title
Bluetooth HAS: NULL-pointer dereference DoS when a bonded peer reconnects before bt_has_register
Summary
The Hearing Access Service (HAS) GATT server in subsys/bluetooth/audio/has.c installs a connection-callback set unconditionally via BT_CONN_CB_DEFINE, so security_changed() runs for every connection that establishes security even before the application has called bt_has_register(). The service attribute pointers hearing_aid_features_attr, preset_control_point_attr, and active_preset_index_attr remain NULL until bt_has_register() resolves them and sets has.registered.
With CONFIG_BT_SETTINGS, settings_set_cb() restores each bonded client's persisted context at boot and unconditionally sets context->flags to BONDED_CLIENT_INIT_FLAGS (non-zero). When a previously bonded peer reconnects and re-establishes security during the startup window before bt_has_register() has been called, security_changed() sees the non-zero flags and schedules notify_work_handler, which calls bt_gatt_is_subscribed() with a still-NULL attribute pointer. That triggers an assertion (__ASSERT(attr, ...) in bt_gatt_is_subscribed()), or a NULL dereference of attr->uuid when assertions are compiled out.
The result is a remotely triggerable (Bluetooth, adjacent) crash of the HAS peripheral. Exploitation requires the peer to have previously bonded with the device and to reconnect within the boot-time race window before the application registers the service; a peer that reconnects persistently can prolong the outage. Impact is denial of service only, with no memory corruption or information disclosure.
The fix adds an early if (!has.registered) { return; } guard in security_changed(), so no notification work is scheduled until the GATT service is registered and its attribute pointers are valid.

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.
