Design/Logic Flaw

A vulnerability in the detection engine of Cisco Adaptive Security Appliance ASA Software and Cisco Firepower Threat Defense FTD Software could allow an unauthenticated, adjacent attacker to send data directly to the kernel of an affected device. The vulnerability exists because the software...

Denial Of Service (DoS)

Linux kernel is vulnerable denial of service DOS attacks. This occurs if an L2 guest was to throw an exception which is not handled by an L1 guest. Guest OS users could cause a system crash by declining to handle an exception thrown by an L2 guest...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. It was found that reporting emulation failures to user space could lead to either a local CVE-2014-7842 or a L2-L1 CVE-2010-5313 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to acce...

Important: kernel

Issue Overview: A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvmioctlcreatedevice, the device holds a reference to a VM object, later this reference is transferred to the caller's file descript...

CVE-2019-1594

A vulnerability in the 802.1X implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service DoS condition on an affected device. The vulnerability is due to incomplete input validation of Extensible Authentication Protocol over LAN EAPOL...

CVE-2019-7221

A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested =1 virtualization is enabled. This high resolution timerhrtimer runs when a L2 guest is active. After VM exit, the syncvmcs12 timer object is stopped. The...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS attacks. The vulnerability exists as a race condition in arch/x86/kvm/x86.c in the Linux kernel before 2.6.38 allows L2 guest OS users to cause a denial of service L1 guest OS crash via a crafted instruction that triggers an L2 emulation failure repor...

Denial Of Service (DoS)

openstack-neutron is vulnerable to denial of service DoS attacks. The vulnerability exists as OpenStack Neutron before 2014.2.4 juno and 2015.1.x before 2015.1.1 kilo, when using the IPTables firewall driver, allows remote authenticated users to cause a denial of service L2 agent crash by adding ...

CVE-2018-0056

If a duplicate MAC address is learned by two different interfaces on an MX Series device, the MAC address learning function correctly flaps between the interfaces. However, the Layer 2 Address Learning Daemon L2ALD daemon might crash when attempting to delete the duplicate MAC address when the...

MX Series: L2ALD daemon may crash if a duplicate MAC is learned by two different interfaces

If a duplicate MAC address is learned by two different interfaces on an MX Series device, the MAC address learning function correctly flaps between the interfaces. However, the Layer 2 Address Learning Daemon L2ALD daemon might crash when attempting to delete the duplicate MAC address when the...

If a duplicate MAC address is learned by two different interfaces on an MX Series device, the MAC address learning function correctly flaps between the interfaces. However, the Layer 2 Address Learning Daemon L2ALD daemon might crash when attempting to delete the duplicate MAC address when the...

KVM Nest Virtualization L1 Guest Privilege Escalation

KVM nested virtualization: privilege escalation in L1 guest When KVM on Intel virtualizes another hypervisor as L1 VM it does not verify that VMX instructions from the L1 VM which trigger a VM exit and are emulated by L0 KVM are coming from ring 0. For code running on bare metal or VMX root mode...

KVM (Nested Virtualization) - L1 Guest Privilege Escalation Vulnerability

Exploit for linux platform in category dos / poc When KVM on Intel virtualizes another hypervisor as L1 VM it does not verify that VMX instructions from the L1 VM which trigger a VM exit and are emulated by L0 KVM are coming from ring 0. For code running on bare metal or VMX root mode this is...

Privilege escalation

An elevation of privilege vulnerability in the Qualcomm kyro L2 driver. Product: Android. Versions: Android kernel. Android ID: A-32831370. References: QC-CR1103158...

CVE-2017-6423

CVE-2017-6423 is an elevation-of-privilege flaw in the Qualcomm Kyro L2 driver within the Android kernel. The vulnerability could allow a local attacker to execute arbitrary code with kernel privileges on affected devices (Pixel and Pixel XL are listed in the Android bulletin). The root cause is ...

Virtuozzo 7 : readykernel-patch (VZA-2017-086)

According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as...

CVE-2017-12154

The preparevmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel through 4.13.3 does not ensure that the "CR8-load exiting" and "CR8-store exiting" L0 vmcs02 controls exist in cases where L1 omits the "use TPR shadow" vmcs12 control, which allows KVM L2 guest OS users to obtain read and write...
