"The version of kernel installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-58007 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: socinfo: Avoid out of
    bounds read of serial number On MSM8916 devices, the serial number exposed in sysfs is constant and does
    not change across individual devices. It's always: db410c:/sys/devices/soc0$ cat serial_number 2644893864
    The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not have support for the serial_num
    field in the socinfo struct. There is an existing check to avoid exposing the serial number in that case,
    but it's not correct: When checking the item_size returned by SMEM, we need to make sure the *end* of the
    serial_num is within bounds, instead of comparing with the *start* offset. The serial_number currently
    exposed on MSM8916 devices is just an out of bounds read of whatever comes after the socinfo struct in
    SMEM. Fix this by changing offsetof() to offsetofend(), so that the size of the field is also taken into
    account. (CVE-2024-58007)

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