The same remote peer also controls the width of the race window by stalling its SMB2 LOGOFF/TREE_DISCONNECT reply.\nAC:L - The attacker drives both sides of the race: the SES_EXITING-while-still-linked window spans blocking SMB round-trips that a malicious server can hold open until the SMB timeout, while referral churn or repeated forced reconnects re-enter the walk at unbounded rate. No condition depends on state outside the attacker\u0027s influence.\nPR:N - A malicious or compromised SMB server holds no privilege on the victim client \u2014 the client authenticates to the server, not the reverse \u2014 so no credentials on the vulnerable component are needed. The alternate local path via `CIFS_GENL_CMD_SWN_NOTIFY` also carries no `GENL_ADMIN_PERM` and is usable by any unprivileged user.\nUI:N - On an already-mounted enterprise SMB share (the normal automounted/persistent case), the DFS refresh worker and reconnect paths run on their own and session teardowns occur automatically via `cifs_prune_tlinks` and DFS failover. No victim action is required at exploitation time.\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The walk reads `ses-\u003echan_count` and `ses-\u003echans[i].server` plus `server-\u003etcpStatus` out of a freed/reallocated `cifs_ses`, and a use-after-free on this object gives control over freed-slab contents, which is leverageable into an arbitrary kernel read primitive against `cifs_ses` state including session and encryption keys.\nI:H - The walk writes into the stale objects \u2014 acquiring `ses-\u003echan_lock` and `ses-\u003echans[i].server-\u003esrv_lock`, then storing `CifsNeedReconnect` into `tcpStatus`. Since the teardown path NULLs `chans[i].server` without `chan_lock` and never lowers `chan_count`, a sprayed replacement object yields a spinlock acquire plus a store at an attacker-chosen address, i.e. a write primitive usable for control-flow hijack.\nA:H - Dereferencing a freed `TCP_Server_Info` and taking `srv_lock` on reclaimed memory reliably produces slab corruption, a spinlock lockup, or an oops/panic, and the trigger can be repeated indefinitely by the remote server."
