  - ksmbd: Fix race condition in RPC handle list access The 'sess->rpc_handle_list' XArray manages RPC handles     within a ksmbd session. Access to this list is intended to be protected by 'sess->rpc_lock' (an     rw_semaphore). However, the locking implementation was flawed, leading to potential race conditions. In     ksmbd_session_rpc_open(), the code incorrectly acquired only a read lock before calling xa_store() and     xa_erase(). Since these operations modify the XArray structure, a write lock is required to ensure     exclusive access and prevent data corruption from concurrent modifications. Furthermore,     ksmbd_session_rpc_method() accessed the list using xa_load() without holding any lock at all. This could     lead to reading inconsistent data or a potential use-after-free if an entry is concurrently removed and     the pointer is dereferenced. Fix these issues by: 1. Using down_write() and up_write() in     ksmbd_session_rpc_open() to ensure exclusive access during XArray modification, and ensuring the lock is     correctly released on error paths. 2. Adding down_read() and up_read() in ksmbd_session_rpc_method() to     safely protect the lookup. (CVE-2025-40039)

Note that Nessus relies on the presence of the package as reported by the vendor.
