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. This flaw affects kernel     versions prior to 5.16 rc2. (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)

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