The version of kernel installed on the remote host is prior to 5.4.209-116.363. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-034 advisory.

    An out-of-bounds write flaw was found in the Linux kernel's framebuffer-based console driver     functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a     local user to crash or potentially escalate their privileges on the system. (CVE-2021-33655)

    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled (CVE-2022-21505)

    A heap buffer overflow flaw was found in the Linux kernel's Netfilter subsystem in the way a user provides     incorrect input of the NFT_DATA_VERDICT type. This flaw allows a local user to crash or potentially     escalate their privileges on the system. (CVE-2022-34918)

    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

    A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses     the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash     the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
    (CVE-2022-36946)

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.
