Descripción técnica

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.

CVE-2026-906223.3 BAJ

—

———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.4h CVE-2026-339703.5 BAJ

———An issue was discovered in NR RRC and L2 in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 1680, W920, W930, W1000, and Modem 5410. In the 5G baseband, a NULL Pointer Dereference occurs when processing a malformed RRC Reconfiguration message.5h CVE-2026-906093.3 BAJ

———A vulnerability has been found in GPAC up to f1219cde. The impacted element is an unknown function of the file scenegraph/vrml_tools.c of the component MP4Box. Such manipulation leads to null pointer dereference. The attack can only be performed from a local environment. The exploit has been disclosed to the public and may be used. Upgrading to version abi-16.23 is sufficient to resolve this issue. The name of the patch is 49dee5cad329cfed310c1682703df7daa47df31a. It is suggested to upgrade the affected component.7h CVE-2026-158917.5 ALT

———The MQTT-SN client keepalive handler process_ping() in subsys/net/lib/mqtt_sn/mqtt_sn.c removes the gateway record after PINGREQ retries are exhausted. It invoked SYS_SLIST_PEEK_HEAD_CONTAINER(&client->gateways, gw, next) but discarded the result. That macro is a pure expression that does not assign to gw, so gw retained its NULL initializer regardless of the list contents. The code then dereferences the NULL gw (gw->gw_id) and passes it to mqtt_sn_gw_destroy(), reaching k_mem_slab_free(&gateways, NULL). With CONFIG_MEM_SLAB_POINTER_VALIDATE enabled this triggers k_panic(); in the default configuration it performs a write through the NULL pointer ((char )mem = slab->free_list;) and corrupts the slab free list. The outcome is a crash/kernel panic or, on targets where address 0 is writable, silent memory-allocator corruption. The vulnerable branch runs whenever the connected MQTT-SN gateway fails to answer keepalive PINGREQs for the configured number of retries. This condition is controlled by the remote peer: a malicious or compromised gateway, or an on-path/adjacent attacker that advertises itself as a gateway and then stops responding (or blackholes the real gateway's PINGRESPs), forces the client into the defect. MQTT-SN runs over UDP and no authentication is required. The impact is a remotely triggerable denial of service (availability) of the affected MQTT-SN client; there is no attacker-controlled data written. The sibling remover process_advertise() uses SYS_SLIST_FOR_EACH_CONTAINER_SAFE and is not affected. The fix assigns the macro's return value to gw.9h CVE-2026-905763.3 BAJ

———A security vulnerability has been detected in GPAC up to f1219cde. Affected is the function gf_node_list_add_child of the file scenegraph/base_scenegraph.c of the component MP4Box. Such manipulation leads to null pointer dereference. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. Upgrading to version abi-16.23 is able to address this issue. The name of the patch is 49dee5cad329cfed310c1682703df7daa47df31a. You should upgrade the affected component.13h CVE-2026-905733.3 BAJ

———A vulnerability was identified in GPAC up to f1219cde. The impacted element is the function gf_sg_mfurl_del of the file scenegraph/vrml_tools.c of the component MP4Box. The manipulation leads to null pointer dereference. Local access is required to approach this attack. The exploit is publicly available and might be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. Upgrading to version abi-16.23 is sufficient to resolve this issue. The identifier of the patch is 49dee5cad329cfed310c1682703df7daa47df31a. It is recommended to upgrade the affected component.14h
