The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6221-1 advisory.

    It was discovered that a race condition existed in the overlay file system implementation in the Linux     kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-20321)

    It was discovered that the virtual terminal (vt) device implementation in the Linux kernel contained a     race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker     could possibly use this to expose sensitive information. (CVE-2021-3753)

    It was discovered that the ext4 file system implementation in the Linux kernel contained a use-after-free     vulnerability. An attacker could use this to construct a malicious ext4 file system image that, when     mounted, could cause a denial of service (system crash). (CVE-2022-1184)

    Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that     some Intel processors with Enhanced Indirect Branch Restricted Speculation (eIBRS) did not properly handle     RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive     information. (CVE-2022-26373)

    Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's     protections against speculative branch target injection attacks were insufficient in some circumstances. A     local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

    It was discovered that the ST NCI NFC driver did not properly handle device removal events. A physically     proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1990)

    It was discovered that the btrfs file system implementation in the Linux kernel did not properly handle     error conditions in some situations, leading to a use-after-free vulnerability. A local attacker could     possibly use this to cause a denial of service (system crash). (CVE-2023-3111)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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