The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5297-1 advisory.

  - In various setup methods of the USB gadget subsystem, there is a possible out of bounds write due to an     incorrect flag check. 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-210292376References: Upstream kernel (CVE-2021-39685)

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

  - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in     the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in     drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a     crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-0330)

  - The vmwgfx driver contains a local privilege escalation vulnerability that allows unprivileged users to     gain access to files opened by other processes on the system through a dangling 'file' pointer.
    (CVE-2022-22942)

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