The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5469-1 advisory.

    It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when     booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot     restrictions. (CVE-2022-21499)

    Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the     removal of stateful expressions 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 execute arbitrary code.
    (CVE-2022-1966)

    Billy Jheng Bing Jhong discovered that the CIFS network file system implementation in the Linux kernel did     not properly validate arguments to ioctl() in some situations. A local attacker could possibly use this to     cause a denial of service (system crash). (CVE-2022-0168)

    Hu Jiahui discovered that multiple race conditions existed in the Advanced Linux Sound Architecture (ALSA)     framework, leading to use-after-free vulnerabilities. A local attacker could use these to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

    Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not     properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use     this to crash the host OS. (CVE-2022-1158)

    It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not     handle detach events properly in some situations, leading to a use-after-free vulnerability. A local     attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1195)

    Duoming Zhou discovered that the 6pack protocol implementation in the Linux kernel did not handle detach     events properly in some situations, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash). (CVE-2022-1198)

    Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not     handle detach events properly in some situations. A local attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2022-1199)

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel during device detach operations. A local attacker could possibly use this to cause a denial of     service (system crash). (CVE-2022-1204)

    Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux     kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a     denial of service (system crash). (CVE-2022-1205)

    Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the kvm implementation in the Linux kernel did     not handle releasing a virtual cpu properly. A local attacker in a guest VM coud possibly use this to     cause a denial of service (host system crash). (CVE-2022-1263)

    It was discovered that the PF_KEYv2 implementation in the Linux kernel did not properly initialize kernel     memory in some situations. A local attacker could use this to expose sensitive information (kernel     memory). (CVE-2022-1353)

    It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate     link layer sessions properly. A local attacker could possibly use this to cause a denial of service     (system crash). (CVE-2022-1516)

    It was discovered that the ACRN Hypervisor Service Module implementation in the Linux kernel did not     properly deallocate memory in some situations. A local privileged attacker could possibly use this to     cause a denial of service (memory exhaustion). (CVE-2022-1651)

    It was discovered that the RxRPC session socket implementation in the Linux kernel did not properly handle     ioctls called when no security protocol is given. A local attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-1671)

    Ziming Zhang discovered that the netfilter subsystem in the Linux kernel did not properly validate sets     with multiple ranged fields. A local attacker could use this to cause a denial of service or execute     arbitrary code. (CVE-2022-1972)

     discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform     reference counting in some error conditions. A local attacker could use this to cause a denial of service.
    (CVE-2022-28356)

    It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly     handle certain error conditions, leading to a double-free. A local attacker could possibly use this to     cause a denial of service (system crash). (CVE-2022-28388)

    It was discovered that the Microchip CAN BUS Analyzer interface implementation in the Linux kernel did not     properly handle certain error conditions, leading to a double-free. A local attacker could possibly use     this to cause a denial of service (system crash). (CVE-2022-28389)

    It was discovered that the EMS CAN/USB interface implementation in the Linux kernel contained a double-     free vulnerability when handling certain error conditions. A local attacker could use this to cause a     denial of service (memory exhaustion). (CVE-2022-28390)
