The version of kernel installed on the remote host is prior to 5.10.82-83.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-008 advisory.

    A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

    A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

    A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

    A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and     bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special     privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. (CVE-2021-4001)

    A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel     through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU     display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when     it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer. (CVE-2021-42327)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5265-1 advisory.

    It was discovered that the KVM implementation for POWER8 processors in the Linux kernel did not properly     keep track if a wakeup event could be resolved by a guest. An attacker in a guest VM could possibly use     this to cause a denial of service (host OS crash). (CVE-2021-43056)

    It was discovered that the TIPC Protocol implementation in the Linux kernel did not properly validate     MSG_CRYPTO messages in some situations. An attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2021-43267)

    It was discovered that the ISDN CAPI implementation in the Linux kernel contained a race condition in     certain situations that could trigger an array out-of-bounds bug. A privileged local attacker could     possibly use this to cause a denial of service or execute arbitrary code. (CVE-2021-43389)

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.

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.
