The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5728-2 advisory.

    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 race condition existed in the memory address space accounting implementation 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-2022-41222)

    It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm     64-bit systems. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-20422)

    It was discovered that the KVM implementation in the Linux kernel did not properly handle virtual CPUs     without APICs in certain situations. A local attacker could possibly use this to cause a denial of service     (host system crash). (CVE-2022-2153)

A     local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

    Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local     attacker could use this to cause a denial of service (system crash) or possibly expose sensitive     information (kernel memory). (CVE-2022-3028)

    It was discovered that the Netlink device interface implementation in the Linux kernel did not properly     handle certain error conditions, leading to a use-after-free vulnerability with some network device     drivers. A local attacker with admin access to the network device could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2022-3625)

    It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any     pending timers during device exit, resulting in 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-2022-3635)

    Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX storage controller driver in the     Linux kernel did not properly handle certain structures. A local attacker could potentially use this to     expose sensitive information (kernel memory). (CVE-2022-40768)

    Snke Huster discovered that a use-after-free vulnerability existed in the WiFi driver stack in the Linux     kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2022-42719)

    A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers     em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system     or potentially escalate their privileges on the system.(CVE-2022-3239)

    An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations.(CVE-2022-39189)
