CVE-2023-4130
Description
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix wrong next length validation of ea buffer in smb2_set_ea()
There are multiple smb2_ea_info buffers in FILE_FULL_EA_INFORMATION request from client. ksmbd find next smb2_ea_info using ->NextEntryOffset of current smb2_ea_info. ksmbd need to validate buffer length Before accessing the next ea. ksmbd should check buffer length using buf_len, not next variable. next is the start offset of current ea that got from previous ea.
