The remote Ubuntu 22.04 LTS / 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6318-1 advisory.

    Daniel Moghimi discovered that some Intel(R) Processors did not properly clear microarchitectural state     after speculative execution of various instructions. A local unprivileged user could use this to obtain to     sensitive information. (CVE-2022-40982)

    Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain     vector register instructions. A local attacker could use this to expose sensitive information.
    (CVE-2023-20593)

    It was discovered that the universal 32bit network packet classifier implementation in the Linux kernel     did not properly perform reference counting in some situations, leading to a use-after-free vulnerability.
    A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-3609)

    It was discovered that the netfilter subsystem in the Linux kernel did not properly handle certain error     conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-3610)

    It was discovered that the Quick Fair Queueing network scheduler implementation in the Linux kernel     contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2023-3611)

    It was discovered that the network packet classifier with netfilter/firewall marks implementation in the     Linux kernel did not properly handle reference counting, leading to a use-after-free vulnerability. A     local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-3776)

    Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle table rules     flush in certain circumstances. A local attacker could possibly use this to cause a denial of service     (system crash) or execute arbitrary code. (CVE-2023-3777)

    Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle rule     additions to bound chains in certain circumstances. A local attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2023-3995)

    It was discovered that the netfilter subsystem in the Linux kernel did not properly handle PIPAPO element     removal, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2023-4004)

    Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle bound chain     deactivation in certain circumstances. A local attacker could possibly use this to cause a denial of     service (system crash) or execute arbitrary code. (CVE-2023-4015)

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.
