high Tenable Self-Hosted Container Security Plugin ID 458879

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: ksmbd: transport_ipc: validate payload
size before reading handle handle_response() dereferences the payload as a 4-byte handle without verifying
that the declared payload size is at least 4 bytes. A malformed or truncated message from ksmbd.mountd can
lead to a 4-byte read past the declared payload size. Validate the size before dereferencing. This is a
minimal fix to guard the initial handle read. (CVE-2025-40084)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
