Official Description
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.
Technical Analysis
CVE-2026-43317 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
