memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125also known as Spectre SWAPGS gadget vulnerability)\n\nA Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with unprivilegedlocal access could use this information to reveal private data through a Spectre-like side channel.\n\nImpact\n\nF5 continues to investigate the impact of the Spectre SWAPGS gadget vulnerability on our products. F5 is focused onproviding patched releases as soon as we have fully tested and verified fixes. F5 will update this article with the most current information as soon as it is confirmed.\n\nBIG-IP\n\nFirst and foremost, there is no exposure on BIG-IP products by way ofthe data plane. All exposure is limited to the control plane (also known as the management plane).\n\nFurthermore, on the control plane, the vulnerability is exploitable only by four authorized, authenticated account roles: Administrator, Resource Administrator, Manager, and iRules Manager. You must be authorized to access the system in one of these roles to even attempt to exploit the vulnerability.\n\nThis vulnerability requires an attacker who can provideand runbinary code of their choosing on the BIG-IP platform.\n\nThese conditions severely restrict the exposure risk of BIG-IP products.\n\nFor single-tenancy products, such as astandalone BIG-IP appliance, the risk is limited to a local, authorized user using this vulnerability to read information from memory that they would not normally be able to access, exceeding their privileges. Effectively, the risk in a single-tenancy situation is that a user may be able to access kernel-space memory, instead of being limited to their own user-space.\n\nFor multi-tenancy environments, such as cloud, VE, and Virtual Clustered Multiprocessing (vCMP), the same local risk applies as with single-tenancy environments local kernel memory access. Additionally, the risk of attacks across guests exists, or attacks against the hypervisor/host. In cloud and VE environments, preventing these new attacks falls on the hypervisor/host platform, outside the scope of F5's ability to support or patch. Please contact your cloud provider or hypervisor vendor to ensure that their platforms or products are protected against this Spectre vulnerability.\n\nFor vCMP environments, F5 believes that while the Spectre SWAPGS gadget vulnerability does offer a theoretical possibility of guest-to-guest or guest-to-host attacks, these would be very difficult to successfully conduct in the BIG-IP environment.\n\nF5 is working with our hardware component vendors to determine the scope of this vulnerability across our various generations of hardware platforms. All of the information we currently have from our vendors is represented in this Security Advisory.\n\nWe are also testing the fixes produced by the Linux community. We are conducting anextensive test campaign to characterize the impact of the fixes on system performance and stabilityto ensure, as best we can, a good experience for our customers. We do not want to rush the process and release fixes without a full understanding of any potential issues. Given the limited exposure, as detailed above, the complexity of the fixes, and the potential issues that we and others have seen, we believe a detailed approach is warranted and that rushing a fix could result in an impact to system stability or unacceptable performance costs. We will update this article with details of our fixes as they become available.\n\nTo determine if this vulnerability affects aplatform and the processor type each platform uses, refer to the following table.\n\nNote : In the following table, only one entry is shown for platform models that may have several variants. For example, BIG-IP 11000, BIG-IP 11050, BIG-IP 11050F, and BIG-IP 11050N are all vulnerable and included in the table as 'BIG-IP 110x0'. Some platforms may have multiple vendor processors, such as the iSeries platforms, which have one or more Intel core processors and may have a vulnerable ARM processor in one or more subsystems. F5 does not believe that ARM processors in these subsystems are accessible to attackers, unless some other code-execution vulnerability is present, but the information is being provided out of an abundance of caution.\n\nModel Processor type Vulnerable to CVE-2019-1125Spectre SWAPGS gadget vulnerability VIPRION B21x0 Intel Y VIPRION B2250 Intel Y VIPRION B4100 AMD Y VIPRION B4200 AMD Y VIPRION B43x0 Intel Y VIPRION B44x0 Intel Y BIG-IP 800 Intel Y BIG-IP 1600 Intel Y BIG-IP 3600 Intel Y BIG-IP 3900 Intel Y BIG-IP2xx0 Intel Y BIG-IP4xx0 Intel Y BIG-IP5xx0 Intel Y BIG-IP7xx0 Intel Y BIG-IP10xx0 Intel Y BIG-IP12xx0 Intel Y BIG-IPi2x00 Intel, ARM Y BIG-IPi4x00 Intel, ARM Y BIG-IPi5x00 Intel, ARM Y BIG-IPi7x00 Intel, ARM Y BIG-IPi10x00 Intel, ARM Y BIG-IP6400 AMD Y BIG-IP6900 AMD Y BIG-IP89x0 AMD Y BIG-IP110x0 AMD Y\n\nNote : Platform models that have reached End of Technical Support (EoTS) will not be evaluated.

This allows a local attacker the ability to use the AF_ALG-based skcipher interface to cause a denial of service (uninitialized-memory free and kernel crash) or have an unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API.

This CVE ID is unique from\n CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)\n\n - An out-of-bounds access issue was found in the Linux\n kernel, all versions through 5.3, in the way Linux\n kernel's KVM hypervisor implements the Coalesced MMIO\n write operation. It operates on an MMIO ring buffer\n 'struct kvm_coalesced_mmio' object, wherein write\n indices 'ring->first' and 'ring->last' value could be\n supplied by a host user-space process. An unprivileged\n host user or process with access to '/dev/kvm' device\n could use this flaw to crash the host kernel, resulting\n in a denial of service or potentially escalating\n privileges on the system. (CVE-2019-14821)\n\n - A buffer overflow flaw was found, in versions from\n 2.6.34 to 5.2.x, in the way Linux kernel's vhost\n functionality that translates virtqueue buffers to IOVs,\n logged the buffer descriptors during migration. A\n privileged guest user able to pass descriptors with\n invalid length to the host when migration is underway,\n could use this flaw to increase their privileges on the\n host. (CVE-2019-14835)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"http://security.gd-linux.com/notice/NS-SA-2019-0200\");\n script_set_attribute(attribute:\"solution\", value:\n\"Upgrade the vulnerable CGSL kernel packages.

the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It could be triggered by an unprivileged local user when a floppy disk was inserted. NOTE: QEMU creates the floppy device by default.\n(bnc#1143191)\n\nCVE-2019-11810: An issue was discovered in the Linux kernel A NULL pointer dereference could occur when megasas_create_frame_pool() failed in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This caused a Denial of Service, related to a use-after-free (bnc#1134399).\n\nCVE-2019-13648: In the Linux kernel on the powerpc platform, when hardware transactional memory was disabled, a local user could cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sent a crafted signal frame.\n(bnc#1142254)\n\nCVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel, a malicious USB device could send an HID report that triggered an out-of-bounds write during generation of debugging messages.
