CVE-2026-97440

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: qrtr: fix node refcount leak on ctrl packet alloc failure

qrtr_send_resume_tx() calls qrtr_node_lookup() which takes a

reference on the returned node. If the subsequent call to

qrtr_alloc_ctrl_packet() fails due to memory allocation failure, the

function returns -ENOMEM without calling qrtr_node_release() to

release the node reference.

Add qrtr_node_release(node) before returning on the allocation failure

path to properly release the reference.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
