In the Linux kernel, the following vulnerability has been resolved: staging: vchiq_core: handle NULL result of find_service_by_handle In case of an invalid handle the function find_servive_by_handle returns NULL. So take care of this and avoid a NULL pointer dereference.

CVE-2026-719227.5 HIG38.6%
——12Multiple DrayTek VigorSwitch models contain a pre-authentication null pointer dereference vulnerability in the setget.cgi interface. The vulnerability is caused by missing validation when the pass field is absent. A remote attacker can trigger this vulnerability via a crafted request to crash the service and cause a denial of service.3dCVE-2026-719204.9 MED32.1%
——10Multiple DrayTek VigorSwitch models contain a null pointer dereference vulnerability in the formlogout function. The vulnerability is caused by missing checks for an empty or absent Cookie header before string handling. A remote attacker can trigger this vulnerability via a crafted request to crash the service and cause a denial of service. Exploitation requires valid administrative credentials for the device's web management interface.3dCVE-2026-132135.3 MED6.5%
——2The 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.3dCVE-2026-781485.3 MED43.1%
——13A vulnerability was determined in ggml-org llama.cpp bec4772f6. This affects the function rpc_server::graph_compute of the file ggml/src/ggml-rpc/ggml-rpc.cpp of the component ggml-RPC Server. Executing a manipulation can lead to null pointer dereference. The attack may be launched remotely. The pull request to fix this issue awaits acceptance.3dCVE-2026-769057.5 HIG28.1%
——8kin-openapi is a Go project for handling OpenAPI files. From 0.10.0 until 0.141.0, openapi3filter.convertParseError in openapi3filter/validation_error_encoder.go dereferences e.Parameter.In without checking whether e.Parameter is nil. A malformed non-string scalar field in a multipart/form-data request body produces a nested ParseError with a nil RequestError.Parameter, and applications that render the validation error through openapi3filter.ConvertErrors or ValidationErrorEncoder panic. An unauthenticated client can repeatedly send such requests to deny service when the application lacks a recovery boundary. JSON request bodies and applications that do not use these error-rendering helpers are not affected. This issue is fixed in version 0.141.0.2dCVE-2026-17251—20.8%
——6A NULL
pointer dereference vulnerability exists in the HTTP request parsing
functionality of
TL-MR6400 v7. An unauthenticated remote attacker can
trigger the vulnerability by sending a specially crafted HTTP request
containing a malformed session cookie header.
Successful
exploitation may cause the HTTP service process to crash, resulting in a
denial-of-service condition and temporary loss of management or CGI
functionality until service recovery.6d
