The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6626-3 advisory.

    Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel     when handling sessions operations. A remote attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2023-32250, CVE-2023-32252, CVE-2023-32257)

    Marek Marczykowski-Grecki discovered that the Xen event channel infrastructure implementation in the     Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a     denial of service (paravirtualized device unavailability). (CVE-2023-34324)

    Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during     device removal. A privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2023-35827)

    Tom Dohrmann discovered that the Secure Encrypted Virtualization (SEV) implementation for AMD processors     in the Linux kernel contained a race condition when accessing MMIO registers. A local attacker in a SEV     guest VM could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2023-46813)

    It was discovered that the Microchip USB Ethernet driver in the Linux kernel contained a race condition     during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could     use this to cause a denial of service (system crash). (CVE-2023-6039)

    It was discovered that the TLS subsystem in the Linux kernel did not properly perform cryptographic     operations in some situations, leading to a null pointer dereference vulnerability. A local attacker could     use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6176)

    Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle dynset     expressions passed from userspace, leading to a null pointer dereference vulnerability. A local attacker     could use this to cause a denial of service (system crash). (CVE-2023-6622)

    It was discovered that the TIPC protocol implementation in the Linux kernel did not properly handle     locking during tipc_crypto_key_revoke() operations. A local attacker could use this to cause a denial of     service (kernel deadlock). (CVE-2024-0641)

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.
