  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix use-after-free in smb2_open during durable reconnect\n\nIn smb2_open, the call to ksmbd_put_durable_fd(fp) drops the reference\nto the durable file descriptor early during the durable reconnect\nprocess. If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails)\nor a scavenger accesses the file, it leads to a use-after-free when\naccessing fp properties (eg fp-\u003ecreate_time).\n\nMove the single put to the end of the function below err_out2 so fp\nstays valid until smb2_open returns.",
