  "description": "In the Linux kernel, the following vulnerability has been resolved:  ovpn: fix peer refcount leak in TCP error paths  When either the TCP RX or TX error path calls ovpn_peer_hold() followed by schedule_work(\u0026peer-\u003Etcp.defer_del_work), and the work item is already pending from the other path, schedule_work() returns false and the work runs only once. Since ovpn_tcp_peer_del_work() calls ovpn_peer_put() exactly once, the extra reference taken by the losing path is never dropped, leaking the peer object.  The race window:    CPU0 (strparser/RX error):       CPU1 (tcp_tx_work/TX error):   ovpn_peer_hold()   \u003C- refcnt\u002B1   ovpn_peer_hold()   \u003C- refcnt\u002B2   schedule_work()    \u003C- queued      schedule_work()    \u003C- NO-OP                                     (work already pending)   ovpn_tcp_peer_del_work runs:     ovpn_peer_del()     ovpn_peer_put()  \u003C- refcnt\u002B1                                    \u003C- peer never freed  Fix by checking the return value of schedule_work() in both paths and calling ovpn_peer_put() to drop the extra reference if the work was already pending. ovpn_peer_hold() is kept unconditional in the TX path as it cannot fail at that point.",
