The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-42244 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-42244 advisory.
- In the Linux kernel, the following vulnerability has been resolved: USB: serial: mos7840: fix crash on
resume Since commit c49cfa917025 (USB: serial: use generic method if no alternative is provided in usb
serial layer), USB serial core calls the generic resume implementation when the driver has not provided
one. This can trigger a crash on resume with mos7840 since support for multiple read URBs was added back
in 2011. Specifically, both port read URBs are now submitted on resume for open ports, but the context
pointer of the second URB is left set to the core rather than mos7840 port structure. Fix this by
implementing dedicated suspend and resume functions for mos7840. Tested with Delock 87414 USB 2.0 to 4x
serial adapter. [ johan: analyse crash and rewrite commit message; set busy flag on resume; drop bulk-in
check; drop unnecessary usb_kill_urb() ] (CVE-2024-42244)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
