CVE-2026-68294

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 ...

CVE-2026-68294

The CVE CVE-2026-68294 affects the Linux kernel QRTR transport (AF_QIPCRTR) by not isolating its global state per network namespace. qrtr_local_nid and qrtr_ports are shared globally and lack namespace checks; qrtr_create() does not restrict the namespace for new sockets. This enables an unprivil...

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...

CVE-2026-52947

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 __radix_tree_create() function in the net/qrtr/af_qrtr.c module of the Linux operating system allows a hacker to cause a service failure.

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...
