A privileged user inside a guest could use these flaws to create denial of service conditions on the host kernel. (CVE-2015-5307, CVE-2015-8104, Important) This update also fixes the following bugs : - On Intel Xeon v5 platforms, the processor frequency was always tied to the highest possible frequency. Switching p-states on these client platforms failed. This update sets the idle frequency, busy frequency, and processor frequency values by determining the range and adjusting the minimal and maximal percent limit values. Now, switching p-states on the aforementioned client platforms proceeds successfully. - Due to a validation error of in-kernel memory-mapped I/O (MMIO) tracing, a VM became previously unresponsive when connected to RHEV Hypervisor. The provided patch fixes this bug by dropping the check in MMIO handler, and a VM continues running as expected. - Due to retry-able command errors, the NVMe driver previously leaked I/O descriptors and DMA mappings. As a consequence, the kernel could become unresponsive during the hot-unplug operation if a driver was removed. This update fixes the driver memory leak bug on command retries, and the kernel no longer hangs in this situation. - The hybrid_dma_data() function was not initialized before use, which caused an invalid memory access when hot-plugging a PCI card. As a consequence, a kernel oops occurred. The provided patch makes sure hybrid_dma_data() is initialized before use, and the kernel oops no longer occurs in this situation. - When running PowerPC (PPC) KVM guests and the host was experiencing a lot of page faults, for example because it was running low on memory, the host sometimes triggered an incorrect kind of interrupt in the guest: a data storage exception instead of a data segment exception. This caused a kernel panic of the PPC KVM guest. With this update, the host kernel synthesizes a segment fault if the corresponding Segment Lookaside Buffer (SLB) lookup fails, which prevents the kernel panic from occurring. - The kernel accessed an incorrect area of the khugepaged process causing Logical Partitioning (LPAR) to become unresponsive, and an oops occurred in medlp5. The backported upstream patch prevents an LPAR hang, and the oops no longer occurs. - When the sctp module was loaded and a route to an association endpoint was removed after receiving an Out-of-The-Blue (OOTB) chunk but before incrementing the last seen 2020-03-18 modified 2015-12-22 plugin id 87583 published 2015-12-22 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/87583 title Scientific Linux Security Update : kernel on SL7.x x86_64 (20151208) NASL family SuSE Local Security Checks NASL id OPENSUSE-2015-893.NASL description This update fixes the following security issues : - bsc#947165 - CVE-2015-7311: xen: libxl fails to honour readonly flag on disks with qemu-xen (xsa-142) - bsc#954405 - CVE-2015-8104: Xen: guest to host DoS by triggering an infinite loop in microcode via #DB exception - bsc#954018 - CVE-2015-5307: xen: x86: CPU lockup during fault delivery (XSA-156) - bsc#950704 - CVE-2015-7970: xen: x86: Long latency populate-on-demand operation is not preemptible (XSA-150) last seen 2020-06-05 modified 2015-12-17 plugin id 87443 published 2015-12-17 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/87443 title openSUSE Security Update : xen (openSUSE-2015-893) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2016-3503.NASL description Description of changes: kernel-uek [2.6.32-400.37.15.el6uek] - ipc/sem.c: fully initialize sem_array before making it visible (Manfred Spraul) [Orabug: 22250043] {CVE-2015-7613} - Initialize msg/shm IPC objects before doing ipc_addid() (Linus Torvalds) [Orabug: 22250043] {CVE-2015-7613} - crypto: add missing crypto module aliases (Mathias Krause) [Orabug: 22249655] {CVE-2013-7421} {CVE-2014-9644} - crypto: include crypto- module prefix in template (Kees Cook) [Orabug: 22249655] {CVE-2013-7421} {CVE-2014-9644} - crypto: prefix module autoloading with last seen 2020-06-01 modified 2020-06-02 plugin id 87836 published 2016-01-11 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/87836 title Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2016-3503) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2016-0024.NASL description Updated kernel packages that fix two security issues and several bugs are now available for Red Hat Enterprise Linux 6.6 Extended Update Support.

This update also fixes the following bugs : * When doing TSO/GSO in the presence of VLAN headers on a macvtap device, the header offsets were incorrectly calculated. As a consequence, when 2 guests on the same host communicated over a guest configured VLAN, performance dropped to about 1 Mbps. A set of patches has been provided to fix this bug, and network performance with VLAN tags now works with optimal performance. (BZ#1215914) * Prior to this update, TSO acceleration features have been removed from the VLAN device which caused that VLAN performance on top of a virtio device was much lower than that of a virtio device itself. This update re-enables TSO acceleration features, and performance of VLAN devices on top of a virtio device has thus been restored. (BZ#1240988) * With an IPv6 address on a bond and a slave failover, Unsolicited Neighbor Advertisement (UNA) was previously sent using the link global IPv6 address as source address. The underlying source code has been patched, and, after the failover in bonding, UNA is sent using both the corresponding link IPv6 address and global IPv6 address of bond0 and bond0.vlan. (BZ#1258480) * Previously, Human Interface Device (HID) would run a report on an unaligned buffer, which could cause a page fault interrupt and an oops when the end of the report was read. This update fixes this bug by padding the end of the report with extra bytes, so the reading of the report never crosses a page boundary. As a result, a page fault and subsequent oops no longer occur. (BZ#1268202) * Inside hugetlb, region data structures were protected by a combination of a memory map semaphore and a single hugetlb instance mutex. However, a page-fault scalability improvement backported to the kernel on previous releases removed the single hugetlb instance mutex and introduced a new mutex table, making the locking combination insufficient, leading to possible race windows that could cause corruption and undefined behavior. The problem could be seen for example with software mapping or re-mapping hugetlb areas with concurrent threads reading/writing to same areas causing page faults. This update fixes the problem by introducing now a required spinlock to the region tracking functions for proper serialization. The problem only affects software using huge pages through hugetlb interface. (BZ#1274597) * Previously, VLAN stacked on the macvlan or macvtap device did not work for devices that implement and use VLAN filters. As a consequence, macvtap passthrough mode failed to transfer VLAN packets over the be2net driver. This update implements VLAN ndo calls to the macvlan driver to pass appropriate VLAN tag IDs to lower devices. As a result, macvtap transfers VLAN packets over be2net successfully. (BZ#1280205) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. last seen 2020-06-01 modified 2020-06-02 plugin id 87886 published 2016-01-13 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/87886 title RHEL 6 : kernel (RHSA-2016:0024) NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-2844-1.NASL description Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors.

Red Hat Product Security 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. * It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #AC (alignment check exception) and #DB (debug exception) is handled. A privileged user inside a guest could use these flaws to create denial of service conditions on the host kernel. (CVE-2015-5307, CVE-2015-8104, Important) Red Hat would like to thank Ben Serebrin of Google Inc. for reporting the CVE-2015-5307 issue. This update also fixes the following bugs : * On Intel Xeon v5 platforms, the processor frequency was always tied to the highest possible frequency. Switching p-states on these client platforms failed. This update sets the idle frequency, busy frequency, and processor frequency values by determining the range and adjusting the minimal and maximal percent limit values. Now, switching p-states on the aforementioned client platforms proceeds successfully. (BZ#1273926) * Due to a validation error of in-kernel memory-mapped I/O (MMIO) tracing, a VM became previously unresponsive when connected to Red Hat Enterprise Virtualization Hypervisor. The provided patch fixes this bug by dropping the check in MMIO handler, and a VM continues running as expected. (BZ#1275150) * Due to retry-able command errors, the NVMe driver previously leaked I/O descriptors and DMA mappings. As a consequence, the kernel could become unresponsive during the hot-unplug operation if a driver was removed. This update fixes the driver memory leak bug on command retries, and the kernel no longer hangs in this situation. (BZ#1279792) * The hybrid_dma_data() function was not initialized before use, which caused an invalid memory access when hot-plugging a PCI card. As a consequence, a kernel oops occurred. The provided patch makes sure hybrid_dma_data() is initialized before use, and the kernel oops no longer occurs in this situation. (BZ#1279793) * When running PowerPC (PPC) KVM guests and the host was experiencing a lot of page faults, for example because it was running low on memory, the host sometimes triggered an incorrect kind of interrupt in the guest: a data storage exception instead of a data segment exception. This caused a kernel panic of the PPC KVM guest. With this update, the host kernel synthesizes a segment fault if the corresponding Segment Lookaside Buffer (SLB) lookup fails, which prevents the kernel panic from occurring. (BZ#1281423) * The kernel accessed an incorrect area of the khugepaged process causing Logical Partitioning (LPAR) to become unresponsive, and an oops occurred in medlp5. The backported upstream patch prevents an LPAR hang, and the oops no longer occurs. (BZ#1281424) * When the sctp module was loaded and a route to an association endpoint was removed after receiving an Out-of-The-Blue (OOTB) chunk but before incrementing the last seen 2020-06-01 modified 2020-06-02 plugin id 87271 published 2015-12-09 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/87271 title Oracle Linux 7 : kernel (ELSA-2015-2552) NASL family Fedora Local Security Checks NASL id FEDORA_2015-F2C534BC12.NASL description kernel-4.1.13-100.fc21 - Linux v4.1.13 - CVE-2015-8104 kvm: DoS infinite loop in microcode DB exception (rhbz 1278496 1279691) - CVE-2015-5307 kvm: DoS infinite loop in microcode AC exception (rhbz 1277172 1279688) Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.

This update also fixes the following bugs : * With an IPv6 address on a bond and a slave failover, Unsolicited Neighbor Advertisement (UNA) was previously sent using the link global IPv6 address as source address. The underlying source code has been patched, and, after the failover in bonding, UNA is sent using both the corresponding link IPv6 address and global IPv6 address of bond0 and bond0.vlan. (BZ#1258479) * Previously, Human Interface Device (HID) would run a report on an unaligned buffer, which could cause a page fault interrupt and an oops when the end of the report was read. This update fixes this bug by padding the end of the report with extra bytes, so the reading of the report never crosses a page boundary. As a result, a page fault and subsequent oops no longer occur.

This update also fixes the following bugs : * On Intel Xeon v5 platforms, the processor frequency was always tied to the highest possible frequency. Switching p-states on these client platforms failed. This update sets the idle frequency, busy frequency, and processor frequency values by determining the range and adjusting the minimal and maximal percent limit values. Now, switching p-states on the aforementioned client platforms proceeds successfully. (BZ#1273926) * Due to a validation error of in-kernel memory-mapped I/O (MMIO) tracing, a VM became previously unresponsive when connected to Red Hat Enterprise Virtualization Hypervisor. The provided patch fixes this bug by dropping the check in MMIO handler, and a VM continues running as expected. (BZ#1275150) * Due to retry-able command errors, the NVMe driver previously leaked I/O descriptors and DMA mappings. As a consequence, the kernel could become unresponsive during the hot-unplug operation if a driver was removed. This update fixes the driver memory leak bug on command retries, and the kernel no longer hangs in this situation. (BZ#1279792) * The hybrid_dma_data() function was not initialized before use, which caused an invalid memory access when hot-plugging a PCI card. As a consequence, a kernel oops occurred. The provided patch makes sure hybrid_dma_data() is initialized before use, and the kernel oops no longer occurs in this situation. (BZ#1279793) * When running PowerPC (PPC) KVM guests and the host was experiencing a lot of page faults, for example because it was running low on memory, the host sometimes triggered an incorrect kind of interrupt in the guest: a data storage exception instead of a data segment exception. This caused a kernel panic of the PPC KVM guest. With this update, the host kernel synthesizes a segment fault if the corresponding Segment Lookaside Buffer (SLB) lookup fails, which prevents the kernel panic from occurring. (BZ#1281423) * The kernel accessed an incorrect area of the khugepaged process causing Logical Partitioning (LPAR) to become unresponsive, and an oops occurred in medlp5. The backported upstream patch prevents an LPAR hang, and the oops no longer occurs.
