Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: smb: Don't leak cfid when reconnect
races with open_cached_dir open_cached_dir() may either race with the tcon reconnection even before
compound_send_recv() or directly trigger a reconnection via SMB2_open_init() or SMB_query_info_init(). The
reconnection process invokes invalidate_all_cached_dirs() via cifs_mark_open_files_invalid(), which
removes all cfids from the cfids->entries list but doesn't drop a ref if has_lease isn't true. This
results in the currently-being-constructed cfid not being on the list, but still having a refcount of 2.
It leaks if returned from open_cached_dir(). Fix this by setting cfid->has_lease when the ref is actually
taken; the cfid will not be used by other threads until it has a valid time. Addresses these kmemleaks:
