smb: prevent use-after-free due to open_cached_dir error paths

...

The vulnerability of the `find_or_create_cached_dir()` function in the fs/smb/client/cached_dir.c module allows a hacker to cause a service failure in Linux-based operating systems with SMB kernel support.

The vulnerability of the findorcreatecacheddir function in the fs/smb/client/cacheddir.c module, which is part of the SMB client support in Linux kernel, relates to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability in the fs/smb/client/cached_dir.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability in the fs/smb/client/cacheddir.c module of the Linux operating system is related to errors during the update of the link counters. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2025-37954

CVE-2025-37954 affects the Linux kernel SMB client logic. The issue is a race in open_cached_dir with lease breaks where a pre-existing valid cfid returned by find_or_create_cached_dir can race with a queued lease break, causing open_cached_dir to treat it as newly constructed and leak a dentry r...

kernel: smb: Initialize cfid->tcon before performing network ops

In the Linux kernel, the following vulnerability has been resolved: smb: Initialize cfid-tcon before performing network ops Avoid leaking a tcon ref when a lease break races with opening the cached directory. Processing the leak break might take a reference to the tcon in cacheddirleasebreak and...
