Keywords: CVE, CVE-2026-43317, CWE-401, CVSS 5.5, EPSS 0.00162

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

most: core: fix leak on early registration failure

A recent commit fixed a resource leak on early registration failures but for some reason left out the first error path which still leaks the resources associated with the interface.

Fix up also the first error path so that the interface is always released on errors.
