CVE-2026-43317: most: core: fix leak on early registration failure
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.

Frequently Asked Questions
What access does an attacker need to exploit this issue?
The CVSS vector indicates local access and low privileges are required. No user interaction is required, and the primary impact is availability.
Which systems should be prioritized for remediation?
Prioritize Linux kernel systems where the MOST core may encounter interface registration errors. The available data does not identify affected kernel versions or specific configurations.
What should be done if the kernel cannot be patched immediately?
A patch is available. The provided information does not specify a workaround or configuration-based mitigation.
