| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free in smb2_open during durable reconnect
In smb2_open, the call to ksmbd_put_durable_fd(fp) drops the reference
to the durable file descriptor early during the durable reconnect
process. If an error occurs subsequently (eg, ksmbd_iov_pin_rsp fails)
or a scavenger accesses the file, it leads to a use-after-free when
accessing fp properties (eg fp->create_time).
Move the single put to the end of the function below err_out2 so fp
stays valid until smb2_open returns. |
