The version of kernel installed on the remote host is prior to 5.15.104-63.140. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-019 advisory.

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

    ext4: block range must be validated before use in ext4_mb_clear_bb() (CVE-2022-50021)

    A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve     local privilege escalation.

    The perf_group_detach function did not check the event's siblings' attach_state before calling     add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching     from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability.

    We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. (CVE-2023-2235)

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

  - In the Linux kernel, the following vulnerability has been resolved: PCI: s390: Fix use-after-free of PCI     resources with per-function hotplug On s390 PCI functions may be hotplugged individually even when they     belong to a multi-function device. In particular on an SR-IOV device VFs may be removed and later re-     added. In commit a50297cf8235 (s390/pci: separate zbus creation from scanning) it was missed however     that struct pci_bus and struct zpci_bus's resource list retained a reference to the PCI functions MMIO     resources even though those resources are released and freed on hot-unplug. These stale resources may     subsequently be claimed when the PCI function re-appears resulting in use-after-free. One idea of fixing     this use-after-free in s390 specific code that was investigated was to simply keep resources around from     the moment a PCI function first appeared until the whole virtual PCI bus created for a multi-function     device disappears. The problem with this however is that due to the requirement of artificial MMIO     addreesses (address cookies) extra logic is then needed to keep the address cookies compatible on re-plug.
    At the same time the MMIO resources semantically belong to the PCI function so tying their lifecycle to     the function seems more logical. Instead a simpler approach is to remove the resources of an individually     hot-unplugged PCI function from the PCI bus's resource list while keeping the resources of other PCI     functions on the PCI bus untouched. This is done by introducing pci_bus_remove_resource() to remove an     individual resource. Similarly the resource also needs to be removed from the struct zpci_bus's resource     list. It turns out however, that there is really no need to add the MMIO resources to the struct     zpci_bus's resource list at all and instead we can simply use the zpci_bar_struct's resource pointer     directly. (CVE-2023-53123)

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