The remote Ubuntu 22.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5754-2 advisory.

It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC     messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2022-43945)

It was discovered that a memory leak existed in the IPv6 implementation of the Linux kernel. A local     attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3524)

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, 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-2022-3564)

It was discovered that the ISDN implementation of the Linux kernel contained a use-after-free     vulnerability. A privileged user could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-3565)

It was discovered that the TCP implementation in the Linux kernel contained a data race condition. An     attacker could possibly use this to cause undesired behaviors. (CVE-2022-3566)

It was discovered that the IPv6 implementation in the Linux kernel contained a data race condition. An     attacker could possibly use this to cause undesired behaviors. (CVE-2022-3567)

It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in the Linux kernel did not     properly handle certain error conditions. A local attacker with physical access could plug in a specially     crafted USB device to cause a denial of service (memory exhaustion). (CVE-2022-3594)

It was discovered that a null pointer dereference existed in the NILFS2 file system implementation in the     Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3621)

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.
