RTU500 has a vulnerability, where high-load scenarios, such as sending GI requests at short intervals, may cause a NULL pointer dereference in the last entry of the enhanced message queue. This can cause a BCI_IEC104 fatal write error, resulting in connection interruption and restart, and ultimately a denial of service for bidirectional IEC 60870-5-104 communication.

CVE-2026-851507.5 HIG—
———A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.16hCVE-2026-782227.5 HIG—
——0A vulnerability exists in NGINX JavaScript where a malformed HTTP response received by ngx.fetch() can crash an NGINX worker when trusted JavaScript reads Response.statusText. Exploitation requires control or influence over the fetched HTTP response.
Impact:
This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system. There is no control plane exposure; this is a data plane issue only.

——0NULL pointer dereference vulnerability in Samsung Open Source mTower allows Pointer Manipulation.
This issue affects mTower: before afef59aa6f55c5d5ebf9b14bc020bf1c2c37489a.3dCVE-2026-828035.3 MED33.7%
——10A vulnerability has been found in armink struct2json 1.0. This affects the function S2J_STRUCT_GET_string_ELEMENT in the library struct2json/inc/s2jdef.h of the component JSON Deserialization. The manipulation of the argument valuestring leads to null pointer dereference. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.2dCVE-2026-825884.3 MED23.3%
——7A vulnerability was identified in Open5GS up to 2.7.7. This issue affects some unknown processing of the file src/amf/namf-handler.c of the component Transfer Endpoint. Such manipulation leads to null pointer dereference. The attack can be launched remotely. Upgrading to version 2.8.0 is capable of addressing this issue. The name of the patch is abf8a836564b966b5141110fc25ed413c4f17522. Upgrading the affected component is advised.3dCVE-2026-814907.7 HIG14.2%
——4A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.3d
