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 ...

kernel: net: qrtr: fix refcount saturation and potential UAF in qrtr_port_remove

A flaw was found in the Linux kernel's qrtr network subsystem. A race condition exists in the qrtrportremove function where the socket reference count is decremented prematurely. This allows a concurrent reader to access a socket whose reference count has dropped to zero, potentially leading to a...

The vulnerability of the qrtr_port_remove() function in the net/qrtr/af_qrtr.c module, which supports Qualcomm IPC cores in the Linux operating system, allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the qrtrportremove function in the net/qrtr/afqrtr.c module, which supports Qualcomm IPC cores in the Linux operating system, is related to errors during link counter updates. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...

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...

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...
