CVE-2026-72308

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A reference count leak occurs in the mlxsw sp port lag join() function. When the mlxsw sp port lag index get() function fails, the system returns an error without releasing the lag reference previously acquired by mlxsw sp lag get(). This results in a memory leak because the reference is not properly dropped via mlxsw sp lag put() as it is in other error paths.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
