Title
ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()
Summary
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16() If ->NameOffset of smb2_create_req is smaller than Buffer offset of smb2_create_req, slab-out-of-bounds read can happen from smb2_open. This patch set the minimum value of the name offset to the buffer offset to validate name length of smb2_create_req().
Severity ?
