The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000892 advisory.

    Buffer overflow in the qeth_snmp_command function in drivers/s390/net/qeth_core_main.c in the Linux kernel     through 3.12.1 allows local users to cause a denial of service or possibly have unspecified other impact     via an SNMP ioctl call with a length value that is incompatible with the command-buffer size.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A buffer overflow flaw was found in the way the qeth_snmp_command() function in the Linux kernel's QETH network device driver implementation handled SNMP IOCTL requests with an out-of-bounds length. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-6381, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the Linux kernel's IPC implementation handled reference counter decrementing. A local, unprivileged user could use this flaw to trigger an Out of Memory (OOM) condition and, potentially, crash the system. (CVE-2013-4483, Moderate)

* It was found that the Xen hypervisor implementation did not correctly check privileges of hypercall attempts made by HVM guests, allowing hypercalls to be invoked from protection rings 1 and 2 in addition to ring 0. A local attacker in an HVM guest able to execute code on privilege levels 1 and 2 could potentially use this flaw to further escalate their privileges in that guest. Note: Xen HVM guests running unmodified versions of Red Hat Enterprise Linux and Microsoft Windows are not affected by this issue because they are known to only use protection rings 0 (kernel) and 3 (userspace). (CVE-2013-4554, Moderate)

* A flaw was found in the way the Linux kernel's Adaptec RAID controller (aacraid) checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions.
(CVE-2013-6383, Moderate)

* It was found that, under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on certain AMD CPUs (for more information, refer to AMD CPU erratum 793 linked in the References section). A privileged user in a guest running under the Xen hypervisor could use this flaw to cause a denial of service on the host system. This update adds a workaround to the Xen hypervisor implementation, which mitigates the AMD CPU issue. Note: this issue only affects AMD Family 16h Models 00h-0Fh Processors. Non-AMD CPUs are not vulnerable. (CVE-2013-6885, Moderate)

* It was found that certain protocol handlers in the Linux kernel's networking implementation could set the addr_len value without initializing the associated data structure. A local, unprivileged user could use this flaw to leak kernel stack memory to user space using the recvmsg, recvfrom, and recvmmsg system calls. (CVE-2013-7263, Low)

* A flaw was found in the way the get_dumpable() function return value was interpreted in the ptrace subsystem of the Linux kernel. When 'fs.suid_dumpable' was set to 2, a local, unprivileged local user could use this flaw to bypass intended ptrace restrictions and obtain potentially sensitive information. (CVE-2013-2929, Low)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The __oom_reap_task_mm function in mm/oom_kill.c in the     Linux kernel, before 4.14.4, mishandles gather     operations. This allows attackers to cause a denial of     service (TLB entry leak or use-after-free) or possibly     have unspecified other impact by triggering a     copy_to_user call within a certain time     window.(CVE-2017-18202i1/4%0

  - Buffer overflow in the qeth_snmp_command function in     drivers/s390/net/qeth_core_main.c in the Linux kernel     through 3.12.1 allows local users to cause a denial of     service or possibly have unspecified other impact via     an SNMP ioctl call with a length value that is     incompatible with the command-buffer     size.(CVE-2013-6381i1/4%0

  - It was discovered that the Linux kernel since 3.6-rc1     with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()     statement in tcp_collapse() function after making a     number of certain syscalls leading to a possible system     crash.(CVE-2016-8645i1/4%0

  - It was found that the Linux kernel's implementation of     vectored pipe read and write functionality did not take     into account the I/O vectors that were already     processed when retrying after a failed atomic access     operation, potentially resulting in memory corruption     due to an I/O vector array overrun. A local,     unprivileged user could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-1805i1/4%0

  - The Linux kernel is vulnerable to an out-of-bounds read     in ext4/balloc.c:ext4_valid_block_bitmap() function. An     attacker could trick a legitimate user or a privileged     attacker could exploit this by mounting a crafted ext4     image to cause a crash.(CVE-2018-1093i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2013-6381 advisory.

  - Buffer overflow in the qeth_snmp_command function in drivers/s390/net/qeth_core_main.c in the Linux kernel     through 3.12.1 allows local users to cause a denial of service or possibly have unspecified other impact     via an SNMP ioctl call with a length value that is incompatible with the command-buffer size.
    (CVE-2013-6381)

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

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h (CVE-2013-2929).

The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application (CVE-2013-2930).

Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c (CVE-2013-4511).

Buffer overflow in the exitcode_proc_write function in arch/um/kernel/exitcode.c in the Linux kernel before 3.12 allows local users to cause a denial of service or possibly have unspecified other impact by leveraging root privileges for a write operation (CVE-2013-4512).

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions (CVE-2013-4514).

The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call (CVE-2013-4515).

Memory leak in the __kvm_set_memory_region function in virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users to cause a denial of service (memory consumption) by leveraging certain device access to trigger movement of memory slots (CVE-2013-4592).

The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-length write operation (CVE-2013-6378).

The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 3.12.1 does not properly validate a certain size value, which allows local users to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command (CVE-2013-6380).

Buffer overflow in the qeth_snmp_command function in drivers/s390/net/qeth_core_main.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service or possibly have unspecified other impact via an SNMP ioctl call with a length value that is incompatible with the command-buffer size (CVE-2013-6381).

The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via a crafted ioctl call (CVE-2013-6383).

The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511 (CVE-2013-6763).
