In the Linux kernel, the following vulnerability has been resolved:

cifs: fix session state check in reconnect to avoid use-after-free issue

Don't collect exiting session in smb2_reconnect_server(), because it will be released soon.

Note that the exiting session will stay in server->smb_ses_list until it complete the cifs_free_ipc() and logoff() and then delete itself from the list.
