UBUNTU-CVE-2026-97440: Medium severity ubuntu/linux vulnerability

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix node refcount leak on ctrl packet alloc failure qrtrsendresumetx() calls qrtrnodelookup() which takes a reference on the returned node. If the subsequent call to qrtrallocctrlpacket() fails due to memory allocation failure, the function returns -ENOMEM without calling qrtrnoderelease() to release the node reference. Add qrtrnoderelease(node) before returning on the allocation failure path to properly release the reference.
