"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-2024-44960 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: usb: gadget: core: Check for unset
    descriptor Make sure the descriptor has been set before looking at maxpacket. This fixes a null pointer
    panic in this case. This May happen if the gadget doesn't properly set up the endpoint for the current
    speed, or the gadget descriptors are malformed and the descriptor for the speed/endpoint are not found. No
    current gadget driver is known to have this problem, but this May cause a hard-to-find bug during
    development of new gadgets. (CVE-2024-44960)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
