The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5790-1 advisory.

  - A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.
    Internal memory locations could be returned to userspace. A local attacker with the permissions to insert     eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit     mitigations in place for the kernel. (CVE-2021-4159)

  - In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-239630375References: Upstream kernel (CVE-2022-20421)

  - Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

  - A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the sch_sfb     enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed)     into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of     service. (CVE-2022-3586)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a     race condition with a resultant use-after-free. (CVE-2022-40307)

  - A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in     drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and     gain escalation of privileges. (CVE-2022-4095)

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