The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - smb: prevent use-after-free due to open_cached_dir error paths If open_cached_dir() encounters an error     parsing the lease from the server, the error handling may race with receiving a lease break, resulting in     open_cached_dir() freeing the cfid while the queued work is pending. Update open_cached_dir() to drop refs     rather than directly freeing the cfid. Have cached_dir_lease_break(), cfids_laundromat_worker(), and     invalidate_all_cached_dirs() clear has_lease immediately while still holding cfids->cfid_list_lock, and     then use this to also simplify the reference counting in cfids_laundromat_worker() and     invalidate_all_cached_dirs(). Fixes this KASAN splat (which manually injects an error and lease break in     open_cached_dir()): ================================================================== BUG: KASAN: slab-     use-after-free in smb2_cached_lease_break+0x27/0xb0 Read of size 8 at addr ffff88811cc24c10 by task     kworker/3:1/65 CPU: 3 UID: 0 PID: 65 Comm: kworker/3:1 Not tainted 6.12.0-rc6-g255cf264e6e5-dirty #87     Hardware name: VMware, Inc.
