CVE-2025-40084

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the ksmbd component. Specifically, the handle response() function does not adequately validate the payload size before attempting to read a handle, potentially leading to a read past the declared payload size when handling malformed or truncated messages from ksmbd.mountd. This issue involves dereferencing the payload as a 4-byte handle without prior size verification.

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