The version of kernel installed on the remote host is prior to 5.10.59-52.142. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-004 advisory.

    2024-11-08: CVE-2021-47354 was added to this advisory.

    2024-06-19: CVE-2021-47322 was added to this advisory.

    2024-06-19: CVE-2021-47325 was added to this advisory.

    2023-11-29: CVE-2023-4732 was added to this advisory.

    A flaw was found in the Linux kernel, where a BPF program can obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel attack. This issue occurs when the protection mechanism     neglects the possibility of uninitialized memory locations on the BPF stack. The highest threat from this     vulnerability is to confidentiality. (CVE-2021-34556)

    A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)

    A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow     the kernel to read uninitialized memory. (CVE-2021-3655)

    A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use     the trace ring buffer in specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could     use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

    A flaw use-after-free in the Linux kernel USB High Speed Mobile Devices functionality was found in the way     user detaches USB device. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2021-37159)

    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

    A flaw was found in the hanging of mounts in the Linux kernel's NFS4 subsystem where remote servers are     unreachable for the client during migration of data from one server to another (during trunking     detection). This flaw allows a remote NFS4 server (if the client is connected) to starve the resources,     causing a denial of service. The highest threat from this vulnerability is to system availability.
    (CVE-2021-38199)

    In the Linux kernel, the following vulnerability has been resolved:

    NFSv4: Fix an Oops in pnfs_mark_request_commit() when doing O_DIRECT (CVE-2021-47322)

    In the Linux kernel, the following vulnerability has been resolved:

    iommu/arm-smmu: Fix arm_smmu_device refcount leak in address translation (CVE-2021-47325)

    In the Linux kernel, the following vulnerability has been resolved:

    drm/sched: Avoid data corruptions (CVE-2021-47354)

    An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)

    A flaw was found in the Linux Kernel's memory management subsytem. In this flaw, A task is exiting and     releasing 2MB page in a vma (vm_area_struct) and hits the BUG statement in pfn_swap_entry_to_page()     referencing pmd_t x. This may allow a local user to crash the Linux kernel. (CVE-2023-4732)

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.
