In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in ksmbd_sessions_deregister() In multichannel mode, UAF issue can occur in session_deregister when the second channel sets up a session through the connection of the first channel. session that is freed through the global session table can be accessed again through ->sessions of connection.
