The remote Ubuntu 16.04 ESM / 18.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6604-2 advisory.

  - A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when     plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to     the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED     controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led     structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
    (CVE-2023-1079)

  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

  - An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)

  - An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6606)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap     out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit     382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

  - A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on     a RCU read locked object which is freed by another thread. We recommend upgrading past commit     e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
