The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5362-1 advisory.

    Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local     attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-25636)

    Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that     hardware mitigations added by ARM to their processors to address Spectre-BTI were insufficient. A local     attacker could potentially use this to expose sensitive information. (CVE-2022-23960)

    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)

    Max Kellermann discovered that the Linux kernel incorrectly handled Unix pipes. A local attacker could     potentially use this to modify any file that could be opened for reading. (CVE-2022-0847)

    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)

    William Liu and Jamie Hill-Daniel discovered that the file system context functionality in the Linux     kernel contained an integer underflow vulnerability, leading to an out-of-bounds write. A local attacker     could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-0185)

    Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that     hardware mitigations added by Intel to their processors to address Spectre-BTI were insufficient. A local     attacker could potentially use this to expose sensitive information. (CVE-2022-0001)

    Jann Horn discovered a race condition in the Unix domain socket implementation in the Linux kernel that     could result in a read-after-free. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2021-4083)

    It was discovered that the NFS server implementation in the Linux kernel contained an out-of-bounds write     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2021-4090)

    Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size     correctly when pre-allocating space in some situations. A local attacker could use this to expose     sensitive information. (CVE-2021-4155)

    It was discovered that the AMD Radeon GPU driver in the Linux kernel did not properly validate writes in     the debugfs file system. A privileged attacker could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2021-42327)

    Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in the Linux kernel did not perform     a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or     possibly execute arbitrary code. (CVE-2022-0330)

    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 VMware Virtual GPU driver in the Linux kernel did not properly handle certain     failure conditions, leading to a stale entry in the file descriptor table. A local attacker could use this     to expose sensitive information or possibly gain administrative privileges. (CVE-2022-22942)

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.
