Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel before version 5.11.11. The qrtrrecvmsg function in net/qrtr/qrtr.c allows attackers to obtain sensitive information from kernel memory due to a partially uninitialized data structure, identified as CID-50535249f624...

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...

CVE-2026-72298

A flaw was found in the Linux kernel's qrtr network component. On 32-bit systems, a 32-bit integer overflow can occur in the qrtrendpointpost function when processing an incoming packet. This overflow can bypass a size validation check, leading to an out-of-bounds write and causing the kernel to...

CVE-2026-68294

In CVE-2026-68294, the Linux kernel QRTR (Qualcomm IPC Router) allows an unprivileged process to create an AF_QIPCRTR socket in a separate network namespace, due to global state (qrtr_local_nid and qrtr_ports) not being partitioned per namespace. This enables cross-namespace QRTR datagrams and co...
