Description

A flaw was found in the Linux kernel. This vulnerability, a Use-After-Free (UAF), occurs in the `fhandle` component when the `may_decode_fh()` function accesses mount namespace information without proper locking. This creates a race condition that could be exploited by an attacker. The most severe consequence is a kernel crash, leading to a Denial of Service (DoS), but it could also result in an endless loop or the disclosure of sensitive information.
