Title
S2OPC through 1.7.3 NULL Pointer Dereference in alloc_notification_message_items()
Summary
S2OPC through 1.7.3 contains a null pointer dereference in msg_subscription_publish_bs__alloc_notification_message_items() where a failed allocation for DataChangeNotification is overwritten by a successful allocation for EventNotificationList. Attackers can trigger heap allocation failures on sessions with both data-change and event notifications to cause the server process to terminate.

Title
GNU libredwg Layer Encoding dwg.spec DWG_TABLE null pointer dereference
Summary
A security flaw has been discovered in GNU libredwg 0.13.4. This impacts the function DWG_TABLE of the file src/dwg.spec of the component Layer Encoding. Performing a manipulation results in null pointer dereference. The attack needs to be approached locally. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.14 will fix this issue. The patch is named f5b548c4c1697d66c3dabd0f6a49280a14365a3a. The affected component should be upgraded. The FIELD_HANDLE macro itself is NULL-safe (emits null_handle) - only the two raw zeroing assignments added by 27118c40 ("encode: also disable LAYER.material") dereferenced a NULL material handle; the fix restores the file's existing if (_obj->style) guard convention for material.

Title
NULL pointer dereference in the Zephyr USB host stack when a device reports zero configurations
Summary
usbh_device_init() in subsys/usb/host/usbh_device.c rejects a device whose device descriptor advertises bNumConfigurations == 0, but it only logs the error and jumps to the cleanup label without setting the return code. At that point the local err is still 0 from the preceding successful descriptor read, so the function returns success while having skipped usbh_device_set_configuration() — the only place udev->cfg_desc is allocated. The device structure is zero-initialised by usbh_device_alloc(), so udev->cfg_desc remains NULL.
usbh_device_connect() treats the zero return as a successful enumeration and calls usbh_class_probe_device(), which starts its descriptor walk from udev->cfg_desc. usbh_desc_get_next_function() passes that NULL pointer to usbh_desc_is_valid(), whose only guard compares the caller-supplied size, so head->bLength is read through a NULL pointer.
The condition is triggered entirely by the attached peripheral: attaching a USB device (or any USB gadget emulating one) that reports bNumConfigurations = 0 reaches the defect directly from the UHC_EVT_DEV_CONNECTED_FS/_HS event handler in subsys/usb/host/usbh_core.c, with no authentication and no user interaction beyond the physical attachment.
On targets where page zero is unmapped or CONFIG_NULL_POINTER_EXCEPTION_DETECTION is enabled this raises a fatal exception in the USB host thread, denying service to the host. Where address zero is readable, the descriptor walker instead parses low memory as a descriptor chain and can dispatch a class probe() with attacker-influenced values, causing further out-of-bounds reads through the still-NULL udev->cfg_desc in usbh_desc_get_iface(). No attacker-controlled write was identified, so the impact is availability plus a bounded out-of-bounds read. Note that CONFIG_USB_HOST_STACK is marked experimental.

Title
IOBit Uninstaller IOCTL Dispatch IURegistryFilter.sys sub_11838 null pointer dereference
Summary
A flaw has been found in IOBit Uninstaller 15.5.0.11. Affected by this issue is the function sub_11838 of the file IURegistryFilter.sys of the component IOCTL Dispatch Handler. This manipulation causes null pointer dereference. The attack requires local access. The exploit has been published and may be used. Identical IURegistryFilter.sys ships across multiple IObit families. The vendor was contacted early about this disclosure but did not respond in any way.

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.
