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-5755-2 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)

    Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA     mappings in some situations, leading to potential data structure reuse. A local attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42703)

    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)
