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.
