Title
ksmbd: fix use-after-free in ksmbd_session_rpc_open
Summary
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in ksmbd_session_rpc_open A UAF issue can occur due to a race condition between ksmbd_session_rpc_open() and __session_rpc_close(). Add rpc_lock to the session to protect it.

No local access is needed at any point.\nAC:L - The attacker drives both sides of the race by pipelining concurrent SMB2 requests on one connection (ksmbd\u0027s workqueue has no per-connection serialization), and the race window spans a blocking userspace IPC round-trip of up to 2 seconds, while the target handle ID is a predictable small `ida_alloc()` value.\nPR:L - Reaching create_smb2_pipe() requires a completed SMB2 SESSION_SETUP and a TREE_CONNECT to IPC$, i.e. any valid low-privileged SMB account (or a guest account where mapping is enabled). This matches the scoring of the sibling ksmbd session UAFs CVE-2025-22040/CVE-2025-22041.\nUI:N - The attacker generates every request in the sequence; no action by a legitimate user or administrator is required to trigger the race.\nS:U - The corruption is confined to the kernel\u0027s own heap and the ksmbd server\u0027s data structures, all within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The success path returns `entry-\u003eid` read from freed slab memory and sends it back to the attacker as the CREATE response VolatileFileId, directly leaking reclaimed kernel heap contents, and the UAF/double-free of a small generic-cache object gives a spray-controlled read primitive.\nI:H - The error path double-frees the entry and calls ksmbd_rpc_id_free() on a stale IDA id now owned by a different live RPC handle, yielding freelist corruption and cross-handle aliasing that are classic stepping stones to arbitrary write and control-flow hijack in kernel context.\nA:H - Use-after-free and double-free of a kmalloc object reliably produce slab corruption, oops, or panic, and the attacker can repeat the race indefinitely over new sessions to crash the server."
