CVE-2026-97440

Estado: RecibidaSin puntuar—

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.
