Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-46026)

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Limit the maximum number of lookups Current code does no bound checking on the number of lookups a client can perform. Though the code restricts the lookups to local clients, there is still a possibility of a...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-52947)

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix refcount saturation and potential UAF in qrtrportremove In qrtrportremove, the socket reference count is decremented via sockput before the port is removed from the qrtrports XArray and before the RCU grace period...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (CVE-2026-46003)

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Limit the total number of nodes Currently, the nameserver doesn't limit the number of nodes it handles. This can be an attack vector if a malicious client starts registering random nodes, leading to memory...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Limit the maximum number of lookups Current code does not perform any bounds checking on the number of lookups a client can perform. Although the code restricts lookups to local clients, there remains a risk that a...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: net: qrtr: The MHI channel should start after the endpoint creation. The MHI channel may generate an event/interrupt immediately after enabling. This can lead to two race condition issues. 1. Such events may be dropped by the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Limit the total number of nodes. Currently, the name server does not limit the number of nodes it handles. This can be a potential attack vector if a malicious client starts registering random nodes, leading to...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: Socket creation is restricted to the initial network namespace. The QRTR protocol maintains its entire port and node state in global variables within the module, without being partitioned per network namespace...

ROS-20261013-73-0171

The vulnerability of the ctrlcmdbye function in the net/qrtr/ns.c module, which supports Qualcomm IPC cores in the Linux operating system, relates to the failure to release resources after their useful lifespan has ended. Exploiting this vulnerability could allow a attacker to cause service...

ROS-20261009-73-0013

The vulnerability of the radixtreecreate function in the net/qrtr/afqrtr.c module of the Linux operating system is related to the failure to release resources after the expiration of their useful life. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel: net: qrtr: restrict socket creation to the initial network namespace

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...
