The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5368-1 advisory.

    It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in     certain situations. A local attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2022-23222)

    It was discovered that the network traffic control implementation in the Linux kernel contained 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-2022-1055)

    Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly     restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain     administrative privileges. (CVE-2022-0492)

    Jrgen Gro discovered that the Xen subsystem within the Linux kernel did not adequately limit the     number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a     driver domain could use this to cause a denial of service in other guest VMs. (CVE-2021-28711,     CVE-2021-28712, CVE-2021-28713)

    Jrgen Gro discovered that the Xen network backend driver in the Linux kernel did not adequately limit     the amount of queued packets when a guest did not process them. An attacker in a guest VM can use this to     cause a denial of service (excessive kernel memory consumption) in the network backend domain.
    (CVE-2021-28714, CVE-2021-28715)

    Szymon Heidrich discovered that the USB Gadget subsystem in the Linux kernel did not properly restrict the     size of control requests for certain gadget types, leading to possible out of bounds reads or writes. A     local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary     code. (CVE-2021-39685)

    It was discovered that a race condition existed in the poll implementation in the Linux kernel, resulting     in 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-2021-39698)

    It was discovered that the simulated networking device driver for the Linux kernel did not properly     initialize memory in certain situations. A local attacker could use this to expose sensitive information     (kernel memory). (CVE-2021-4135)

    Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not     perform permission checks correctly in some situations. A local attacker could possibly use this to gain     administrative privileges. (CVE-2021-4197)

    Brendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device driver in the Linux kernel did     not properly validate meta-data coming from the device. A local attacker who can control an emulated     device can use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2021-43975)

    It was discovered that the ARM Trusted Execution Environment (TEE) subsystem in the Linux kernel contained     a race condition leading to a use- after-free vulnerability. A local attacker could use this to cause a     denial of service or possibly execute arbitrary code. (CVE-2021-44733)

    It was discovered that the Phone Network protocol (PhoNet) implementation in the Linux kernel did not     properly perform reference counting in some error conditions. A local attacker could possibly use this to     cause a denial of service (memory exhaustion). (CVE-2021-45095)

    It was discovered that the eBPF verifier in the Linux kernel did not properly perform bounds checking on     mov32 operations. A local attacker could use this to expose sensitive information (kernel pointer     addresses). (CVE-2021-45402)

    It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel did     not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause     a denial of service (memory exhaustion). (CVE-2021-45480)

    It was discovered that the BPF subsystem in the Linux kernel did not properly track pointer types on     atomic fetch operations in some situations. A local attacker could use this to expose sensitive     information (kernel pointer addresses). (CVE-2022-0264)

    It was discovered that the TIPC Protocol implementation in the Linux kernel did not properly initialize     memory in some situations. A local attacker could use this to expose sensitive information (kernel     memory). (CVE-2022-0382)

    Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in     the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a     denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435)

    It was discovered that the KVM implementation for s390 systems in the Linux kernel did not properly     prevent memory operations on PVM guests that were in non-protected mode. A local attacker could use this     to obtain unauthorized memory write access. (CVE-2022-0516)

    It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in     certain situations. A remote attacker could possibly use this to cause a denial of service (memory     exhaustion). (CVE-2022-0742)

    It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough     memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
