CVE-2023-39176

Name of the Vulnerable Software and Affected Versions Linux Kernel ksmbd module (affected versions not specified)

Description A flaw was found in 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
