An integer overflow vulnerability was found in xt_alloc_table_info, which on 32-bit systems can lead to small structure allocation and a copy_from_user based heap corruption. (CVE-2016-3135)
In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it is possible for a user-supplied ipt_entry structure to have a large next_offset field. This field is not bounds checked prior to writing a counter value at the supplied offset. (CVE-2016-3134)
A weakness was found in the Linux ASLR implementation. Any user able to run 32-bit applications in a x86 machine can disable the ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672)
Destroying a network interface with a large number of IPv4 addresses keeps a rtnl_lock for a very long time, which can block many network-related operations. (CVE-2016-3156)
A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.
(CVE-2016-7117)
(Updated on 2017-01-19: CVE-2016-7117 was fixed in this release but was previously not part of this errata.)

Space precludes documenting all\nof these bug fixes in this advisory. To see the complete list of bug fixes,\nusers are directed to the linked Knowledge Article.\n\nSecurity Fix(es):\n\n * A use-after-free vulnerability was found in the kernel's socket recvmmsg\nsubsystem. This may allow remote attackers to corrupt memory and may allow\nexecution of arbitrary code. This corruption takes place during the error\nhandling routines within __sys_recvmmsg() function. (CVE-2016-7117,\nImportant)\n\n * A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and\nother tcp_* functions. This condition could allow an attacker to send an\nincorrect selective acknowledgment to existing connections, possibly\nresetting a connection. (CVE-2016-6828, Moderate)\n\n * A flaw was found in the Linux kernel's implementation of the SCTP\nprotocol. A remote attacker could trigger an out-of-bounds read with an\noffset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es):\n\n * Previously, the performance of Internet Protocol over InfiniBand (IPoIB)\nwas suboptimal due to a conflict of IPoIB with the Generic Receive Offload\n(GRO) infrastructure. With this update, the data cached by the IPoIB driver\nhas been moved from a control block into the IPoIB hard header, thus\navoiding the GRO problem and the corruption of IPoIB address information.\nAs a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n * Previously, when a virtual machine (VM) with PCI-Passthrough interfaces\nwas recreated, a race condition between the eventfd daemon and the virqfd\ndaemon occurred. Consequently, the operating system rebooted. This update\nfixes the race condition. As a result, the operating system no longer\nreboots in the described situation. (BZ#1391611)\n\n * Previously, a packet loss occurred when the team driver in round-robin\nmode was sending a large number of packets.

Space precludes documenting all\nof these bug fixes in this advisory. To see the complete list of bug fixes,\nusers are directed to the related Knowledge Article.\n\nSecurity Fix(es):\n\n * A use-after-free vulnerability was found in the kernel's socket recvmmsg\nsubsystem. This may allow remote attackers to corrupt memory and may allow\nexecution of arbitrary code. This corruption takes place during the error\nhandling routines within __sys_recvmmsg() function. (CVE-2016-7117,\nImportant)\n\n * A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and\nother tcp_* functions. This condition could allow an attacker to send an\nincorrect selective acknowledgment to existing connections, possibly\nresetting a connection. (CVE-2016-6828, Moderate)\n\n * A flaw was found in the Linux kernel's implementation of the SCTP\nprotocol. A remote attacker could trigger an out-of-bounds read with an\noffset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es):\n\n * Previously, the performance of Internet Protocol over InfiniBand (IPoIB)\nwas suboptimal due to a conflict of IPoIB with the Generic Receive Offload\n(GRO) infrastructure. With this update, the data cached by the IPoIB driver\nhas been moved from a control block into the IPoIB hard header, thus\navoiding the GRO problem and the corruption of IPoIB address information.\nAs a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n * Previously, when a virtual machine (VM) with PCI-Passthrough interfaces\nwas recreated, a race condition between the eventfd daemon and the virqfd\ndaemon occurred. Consequently, the operating system rebooted. This update\nfixes the race condition. As a result, the operating system no longer\nreboots in the described situation. (BZ#1391611)\n\n * Previously, a packet loss occurred when the team driver in round-robin\nmode was sending a large number of packets. This update fixes counting of\nthe packets in the round-robin runner of the team driver, and the packet\nloss no longer occurs in the described situation. (BZ#1392023)\n\n * Previously, the virtual network devices contained in the deleted\nnamespace could be deleted in any order. If the loopback device was not\ndeleted as the last item, other netns devices, such as vxlan devices, could\nend up with ...\n\n Description truncated, please see the referenced URL(s) for more

A typical process filling 4096 pipes with 1 MB of data will use 4 GB of memory and there can be multiple such processes, up to a per-user-limit.\n(CVE-2016-2847, Moderate)\n\nRed Hat would like to thank Tetsuo Handa for reporting CVE-2016-2847.\n\nBug Fix(es) :\n\n* Previously, an XFS corruption in some cases occurred on Seagate 8TB drive based volumes after a planned system shutdown or reboot, when a disk write back cache was used. With this update, the megaraid_sas driver has been fixed and the XFS corruption no longer occurs in the described scenario. (BZ#1398178)\n\n* This update applies a set of patches for the resizable hash table (rhashtable). This set contains backported bug fixes and enhancements from upstream. (BZ#1382630)\n\n* Previously, a kernel panic in some cases occurred during the boot with the Nonvolatile Memory Express (NVMe) kernel module, because the NVMe driver did not receive legacy PCI interrupts. This update fixes the NVMe driver to always use the Message Signaled Interrupts (MSI/MSI-X) interrupts. As a result, the operating system now boots without panic under the described circumstances. (BZ#1396558)\n\n* Previously, the Advanced Error Reporting (AER) correct error in some cases caused a kernel panic. This update fixes the\n_scsih_pci_mmio_enabled() function in the mpt3sas driver to not incorrectly return PCI_ERS_RESULT_NEED_RESET return value in the situation when PCI_ERS_RESULT_RECOVERED return value is expected. As a result, the kernel no longer panics due to _scsih_pci_mmio_enabled().\n(BZ#1395220)\n\n* When resizing the Transmit (TX) and Receive (RX) rings in the sfc driver with the 'ethtool -G' command, a kernel protection fault in the napi_hash_add() function occurred on systems with a large number of queues. With this update, the efx_copy_channel()function in the sfc driver has been fixed to correctly clear the napi_hash state. As a result, the sfc kernel module now unloads successfully without the mentioned kernel protection fault. (BZ#1401460)\n\n* When a virtual machine (VM) with 2 PCI-Passthrough Ethernet interfaces attached was created, deleted and recreated, the operating system terminated unexpectedly and rebooted during the recreation.\nThis update fixes the race condition between the eventfd and virqfd signaling mechanisms in the vfio driver. As a result, the operating system now boots without crashing in the described situation.\n(BZ#1391610)\n\n* Previously, when two NFS shares with different security settings were mounted, the I/O operations to the kerberos-authenticated mount caused the RPC_CRED_KEY_EXPIRE_SOON parameter to be set, but the parameter was not unset when performing the I/O operations on the sec=sys mount. Consequently, writes to both NFS shares had the same parameters, regardless of their security settings. This update fixes this problem by moving the NO_CRKEY_TIMEOUT parameter to the auth->au_flags field. As a result, NFS shares with different security settings are now handled as expected. (BZ# 1388603)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398588)", "cvss3": {"exploitabilityScore": 3.9, "cvssV3": {"baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2017-02-01T00:00:00", "type": "nessus", "title": "RHEL 7 : kernel (RHSA-2017:0217)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 10.0, "vectorString": "AV:N/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2016-2847", "CVE-2016-7117"], "modified": "2019-10-24T00:00:00", "cpe": ["p-cpe:/a:redhat:enterprise_linux:kernel", "p-cpe:/a:redhat:enterprise_linux:kernel-abi-whitelists", "p-cpe:/a:redhat:enterprise_linux:kernel-debug", "p-cpe:/a:redhat:enterprise_linux:kernel-debug-debuginfo", "p-cpe:/a:redhat:enterprise_linux:kernel-debug-devel", "p-cpe:/a:redhat:enterprise_linux:kernel-debuginfo", "p-cpe:/a:redhat:enterprise_linux:kernel-debuginfo-common-s390x", "p-cpe:/a:redhat:enterprise_linux:kernel-debuginfo-common-x86_64", "p-cpe:/a:redhat:enterprise_linux:kernel-devel", "p-cpe:/a:redhat:enterprise_linux:kernel-doc", "p-cpe:/a:redhat:enterprise_linux:kernel-headers", "p-cpe:/a:redhat:enterprise_linux:kernel-kdump", "p-cpe:/a:redhat:enterprise_linux:kernel-kdump-debuginfo", "p-cpe:/a:redhat:enterprise_linux:kernel-kdump-devel", "p-cpe:/a:redhat:enterprise_linux:kernel-tools", "p-cpe:/a:redhat:enterprise_linux:kernel-tools-debuginfo", "p-cpe:/a:redhat:enterprise_linux:kernel-tools-libs", "p-cpe:/a:redhat:enterprise_linux:kernel-tools-libs-devel", "p-cpe:/a:redhat:enterprise_linux:perf", "p-cpe:/a:redhat:enterprise_linux:perf-debuginfo", "p-cpe:/a:redhat:enterprise_linux:python-perf", "p-cpe:/a:redhat:enterprise_linux:python-perf-debuginfo", "cpe:/o:redhat:enterprise_linux:7.2"], "id": "REDHAT-RHSA-2017-0217.NASL", "href": "https://www.tenable.com/plugins/nessus/96922", "sourceData": "#\n# (C) Tenable Network Security, Inc.\n#\n# The descriptive text and package checks in this plugin were \n# extracted from Red Hat Security Advisory RHSA-2017:0217.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of sctp protocol in which a remote attacker can trigger an out of bounds read with an offset of up to 64kB. This may panic the machine with a page-fault. (CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The kernel-rt packages have been upgraded to the 3.10.0-514.6.1 source tree, which provides a number of bug fixes over the previous version. (BZ# 1401863)\n\n* Previously, the device mapper (DM) subsystem was not notified that the real-time kernel changes the way preemption works with spinlocks.\nThis caused a kernel panic when the dm-multipath kernel module was loaded because the interrupt request (IRQ) check was invalid on the real-time kernel. This check has been corrected enabling the system to boot correctly with the dm-multipath module enabled. (BZ#1400930)\n\n* Unlike the standard Linux kernel, the real-time kernel does not disable interrupts inside the Interrupt Service Routines driver.\nBecause of this difference, a New API (NAPI) function for turning interrupt requests (IRQ) off was actually being called with IRQs enabled.

(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The kernel-rt packages have been upgraded to the 3.10.0-514.6.1\nsource tree, which provides a number of bug fixes over the previous\nversion. (BZ# 1401863)\n\n* Previously, the device mapper (DM) subsystem was not notified that\nthe real-time kernel changes the way preemption works with spinlocks.\nThis caused a kernel panic when the dm-multipath kernel module was\nloaded because the interrupt request (IRQ) check was invalid on the\nreal-time kernel. This check has been corrected enabling the system to\nboot correctly with the dm-multipath module enabled. (BZ#1400930)\n\n* Unlike the standard Linux kernel, the real-time kernel does not\ndisable interrupts inside the Interrupt Service Routines driver.\nBecause of this difference, a New API (NAPI) function for turning\ninterrupt requests (IRQ) off was actually being called with IRQs\nenabled. Consequently, the NAPI poll list was being corrupted, causing\nimproper networking card operation and potential kernel hangs. With\nthis update, the NAPI function has been corrected to force\nmodifications of the poll list to be protected allowing proper\noperation of the networking card drivers.

This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\n* A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* Previously, the performance of Internet Protocol over InfiniBand (IPoIB) was suboptimal due to a conflict of IPoIB with the Generic Receive Offload (GRO) infrastructure. With this update, the data cached by the IPoIB driver has been moved from a control block into the IPoIB hard header, thus avoiding the GRO problem and the corruption of IPoIB address information. As a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted. This update fixes the race condition. As a result, the operating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and the packet loss no longer occurs in the described situation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted namespace could be deleted in any order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan devices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a result, the kernel oops no longer occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of 0xA149 showed the following warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing by Red Hat and might not be certified. Please consult https:/ /hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system now boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive after a long run. This was caused by a race condition between the try_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating system no longer locks up in the described scenario. (BZ#1393719)\n\nNote that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory.

With this update, the data\ncached by the IPoIB driver has been moved from a control block into\nthe IPoIB hard header, thus avoiding the GRO problem and the\ncorruption of IPoIB address information. As a result, the performance\nof IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough\ninterfaces was recreated, a race condition between the eventfd daemon\nand the virqfd daemon occurred. Consequently, the operating system\nrebooted. This update fixes the race condition. As a result, the\noperating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in\nround-robin mode was sending a large number of packets. This update\nfixes counting of the packets in the round-robin runner of the team\ndriver, and the packet loss no longer occurs in the described\nsituation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted\nnamespace could be deleted in any order. If the loopback device was\nnot deleted as the last item, other netns devices, such as vxlan\ndevices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended\nby a kernel oops. With this update, the underlying source code has\nbeen fixed to ensure the correct order when deleting the virtual\nnetwork devices on netns deletion. As a result, the kernel oops no\nlonger occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform\nController Hub (PCH) with a PCI device ID of 0xA149 showed the\nfollowing warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake\nprocessor with unknown PCH - this hardware has not undergone testing\nby Red Hat and might not be certified. Please consult https:/\n/hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system\nnow boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive\nafter a long run. This was caused by a race condition between the\ntry_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating\nsystem no longer locks up in the described scenario.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.\n(CVE-2016-7117, Important)\n\n* An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998, Moderate)\n\n* A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.\n(CVE-2016-6828, Moderate)\n\nBug Fix(es) :\n\n* When parallel NFS returned a file layout, a kernel crash sometimes occurred. This update removes the call to the BUG_ON() function from a code path of a client that returns the file layout. As a result, the kernel no longer crashes in the described situation. (BZ#1385480)\n\n* When a guest virtual machine (VM) on Microsoft Hyper-V was set to crash on a Nonmaskable Interrupt (NMI) that was injected from the host, this VM became unresponsive and did not create the vmcore dump file. This update applies a set of patches to the Virtual Machine Bus kernel driver (hv_vmbus) that fix this bug. As a result, the VM now first creates and saves the vmcore dump file and then reboots.\n(BZ#1385482)\n\n* From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values. (BZ# 1391974)\n\n* When using the ixgbe driver and the software Fibre Channel over Ethernet (FCoE) stack, suboptimal performance in some cases occurred on systems with a large number of CPUs. This update fixes the fc_exch_alloc() function to try all the available exchange managers in the list for an available exchange ID. This change avoids failing allocations, which previously led to the host busy status.\n(BZ#1392818)\n\n* When the vmwgfx kernel module loads, it overrides the boot resolution automatically. Consequently, users were not able to change the resolution by manual setting of the kernel's 'vga=' parameter in the /boot/grub/ grub.conf file. This update adds the 'nomodeset' parameter, which can be set in the /boot/grub/grub.conf file. The 'nomodeset' parameter allows the users to prevent the vmwgfx driver from loading. As a result, the setting of the 'vga=' parameter works as expected, in case that vmwgfx does not load. (BZ#1392875)\n\n* When Red Hat Enterprise Linux 6.8 was booted on SMBIOS 3.0 based systems, Desktop Management Interface (DMI) information, which is referenced by several applications, such as NEC server's memory RAS utility, was missing entries in the sysfs virtual file system. This update fixes the underlying source code, and sysfs now shows the DMI information as expected. (BZ# 1393464)\n\n* Previously, bonding mode active backup and the propagation of the media access control (MAC) address to a VLAN interface did not work in Red Hat Enterprise Linux 6.8, when the fail_over_mac bonding parameter was set to fail_over_mac=active. With this update, the underlying source code has been fixed so that the VLANs continue inheriting the MAC address of the active physical interface until the VLAN MAC address is explicitly set to any value. As a result, IPv6 EUI64 addresses for the VLAN can reflect any changes to the MAC address of the physical interface, and Duplicate Address Detection (DAD) behaves as expected.

As a result, the performance of IPoIB has been improved. (BZ#1390668)\n\n* Previously, when a virtual machine (VM) with PCI-Passthrough interfaces was recreated, a race condition between the eventfd daemon and the virqfd daemon occurred. Consequently, the operating system rebooted. This update fixes the race condition. As a result, the operating system no longer reboots in the described situation.\n(BZ#1391611)\n\n* Previously, a packet loss occurred when the team driver in round-robin mode was sending a large number of packets. This update fixes counting of the packets in the round-robin runner of the team driver, and the packet loss no longer occurs in the described situation. (BZ#1392023)\n\n* Previously, the virtual network devices contained in the deleted namespace could be deleted in any order. If the loopback device was not deleted as the last item, other netns devices, such as vxlan devices, could end up with dangling references to the loopback device.\nConsequently, deleting a network namespace (netns) occasionally ended by a kernel oops. With this update, the underlying source code has been fixed to ensure the correct order when deleting the virtual network devices on netns deletion. As a result, the kernel oops no longer occurs under the described circumstances. (BZ#1392024)\n\n* Previously, a Kabylake system with a Sunrise Point Platform Controller Hub (PCH) with a PCI device ID of 0xA149 showed the following warning messages during the boot :\n\n'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing by Red Hat and might not be certified. Please consult https:/ /hardware.redhat.com for certified hardware.'\n\nThe messages were shown because this PCH was not properly recognized.\nWith this update, the problem has been fixed, and the operating system now boots without displaying the warning messages. (BZ#1392033)\n\n* Previously, the operating system occasionally became unresponsive after a long run. This was caused by a race condition between the try_to_wake_up() function and a woken up task in the core scheduler.\nWith this update, the race condition has been fixed, and the operating system no longer locks up in the described scenario.

With this update, the underlying\n source code has been fixed so that the VLANs continue\n inheriting the MAC address of the active physical\n interface until the VLAN MAC address is explicitly set\n to any value. As a result, IPv6 EUI64 addresses for the\n VLAN can reflect any changes to the MAC address of the\n physical interface, and Duplicate Address Detection\n (DAD) behaves as expected.\"\n );\n # https://listserv.fnal.gov/scripts/wa.exe?A2=ind1701&L=scientific-linux-errata&F=&S=&P=3224\n script_set_attribute(\n attribute:\"see_also\",\n value:\"http://www.nessus.org/u?6d1f3c8c\"\n );\n script_set_attribute(attribute:\"solution\", value:\"Update the affected packages.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:POC/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:P/RL:O/RC:C\");\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n script_set_attribute(attribute:\"metasploit_name\", value:'Linux Kernel 4.6.3 Netfilter Privilege Escalation');\n script_set_attribute(attribute:\"exploit_framework_metasploit\", value:\"true\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-abi-whitelists\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-debuginfo\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:fermilab:scientific_linux:kernel-debug-devel\");\n script_set_attribute(attribute:\"
