CVE-2023-4130 Details
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.
A vulnerability in the Linux kernel's ksmbd component relates to improper validation of buffer lengths for extended attributes in SMB2 FILE_FULL_EA_INFORMATION requests. This issue can lead to incorrect processing of multiple smb2_ea_info buffers, potentially causing errors or unexpected behavior.
Users can upgrade to the latest stable version of the Linux kernel to address this vulnerability.
