The version of kernel installed on the remote host is prior to 4.14.262-200.489. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1749 advisory.

    A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was     found in the way users call some interrupts with high frequency from one of the guests.A local user could     use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711)

(CVE-2021-28713)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: The timeout could even never trigger if the guest manages to have only one free     slot in its RX queue ring page and the next package would require more than one free slot, which may be     the case when using GSO, XDP, or software hashing. (CVE-2021-28714)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    (CVE-2021-4083)

    A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

    A use-after-free flaw in the Linux kernel TEE (Trusted Execution Environment) subsystem was found in the     way user calls ioctl TEE_IOC_OPEN_SESSION or TEE_IOC_INVOKE. A local user could use this flaw to crash the     system or escalate their privileges on the system. If the Linux system non configured with the     CONFIG_PREEMPT option or CONFIG_CPU_SW_DOMAIN_PAN option enabled, then it is unlikely that a user can     trigger this issue. (CVE-2021-44733)

The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1782146775 advisory.

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)

  - Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of     privilege via adjacent access. (CVE-2020-12351)

  - Improper access control in BlueZ may allow an unauthenticated user to potentially enable information     disclosure via adjacent access. (CVE-2020-12352)

  - Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of     service via adjacent access. This affects all Linux kernel versions that support BlueZ. (CVE-2020-24490)

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

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1783337441 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: IB/qib: Protect from buffer overflow     in struct qib_user_sdma_pkt fields Overflowing either addrlimit or bytes_togo can allow userspace to     trigger a buffer overflow of kernel memory. Check for overflows in all the places doing math on user     controlled buffers. (CVE-2021-47485)

  - In the Linux kernel, the following vulnerability has been resolved: nfsd: fix use-after-free due to     delegation race A delegation break could arrive as soon as we've called vfs_setlease. A delegation break     runs a callback which immediately (in nfsd4_cb_recall_prepare) adds the delegation to del_recall_lru. If     we then exit nfs4_set_delegation without hashing the delegation, it will be freed as soon as the callback     is done with it, without ever being removed from del_recall_lru. Symptoms show up later as use-after-free     or list corruption warnings, usually in the laundromat thread. I suspect aba2072f4523 nfsd: grant read     delegations to clients holding writes made this bug easier to hit, but I looked as far back as v3.0 and     it looks to me it already had the same problem. So I'm not sure where the bug was introduced; it may have     been there from the beginning. (CVE-2021-47506)

  - In the Linux kernel, the following vulnerability has been resolved: proc/vmcore: fix clearing user buffer     by properly using clear_user() To clear a user buffer we cannot simply use memset, we have to use     clear_user(). With a virtio-mem device that registers a vmcore_cb and has some logically unplugged memory     inside an added Linux memory block, I can easily trigger a BUG by copying the vmcore via cp: systemd[1]:

    SMAP triggers a permissions violation on wrong access. In the x86-64 variant of clear_user(), SMAP is     properly handled via clac()+stac(). To fix, properly use clear_user() when we're dealing with a user     buffer. (CVE-2021-47566)

  - In the Linux kernel, the following vulnerability has been resolved: staging: rtl8192e: Fix use after free     in _rtl92e_pci_disconnect() The free_rtllib() function frees the dev pointer so there is use after free     on the next line. Re-arrange things to avoid that. (CVE-2021-47571)

  - In the Linux kernel, the following vulnerability has been resolved: scsi: scsi_debug: Sanity check block     descriptor length in resp_mode_select() In resp_mode_select() sanity check the block descriptor len to     avoid UAF.
