Ubuntu.comUB:CVE-2023-52442CVE-2023-52442
In the Linux kernel, the following vulnerability has been resolved: ksmbd:
validate session id and tree id in compound request smb2_get_msg() in
smb2_get_ksmbd_tcon() and smb2_check_user_session() will always return the
first request smb2 header in a compound request. if SMB2_TREE_CONNECT_HE
is the first command in compound request, will return 0, i.e. The tree id
check is skipped. This patch use ksmbd_req_buf_next() to get current
command in compound.
