CVE-2023-39176: Linux Kernel ksmbd Transform Header Out-Of-Bounds Read Information Disclosure Vulnerability

First published: Fri Nov 15 2024(Updated: )

A flaw was found within the parsing of SMB2 requests that have a transform header in the kernel ksmbd module. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this to disclose sensitive information on affected installations of Linux. Only systems with ksmbd enabled are vulnerable to this CVE.
