4 Steps to Creating a Powerful Research Lab for Reverse Engineering

However, manual lab setup and configuration can prove to be a laborious and time-consuming process. In this article, we'll look at 4 ways to create a reverse engineering lab, discuss how to save time, and, potentially, improve the detection rate using a sandbox-as-a-service, and a recommended lis...

USN-5980-1 linux, linux-aws, linux-azure, linux-gcp, linux-gke, linux-gkeop, linux-ibm, linux-kvm, linux-oracle, linux-raspi vulnerabilities

It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service memory exhaustion. CVE-2021-3669 It was discovered that the KVM VMX implementation in the Linux kernel did no...

USN-5979-1 linux-hwe-5.19 vulnerabilities

It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. CVE-2022-2196 It was discovered...

The vulnerability of the kvm_vcpu_ioctl_x86_getdebugregss() function (arch/x86/kvm/x86.c) in the KVM virtualization subsystem of the Linux operating system allows a attacker to gain access to protected information.

The vulnerability of the kvmvcpuioctlx86getdebugregss function arch/x86/kvm/x86.c in the KVM virtualization subsystem of the Linux operating system is related to errors during initialization. Exploiting this vulnerability can allow an attacker to gain access to protected information...

USN-5977-1 linux-oem-6.0 vulnerabilities

It was discovered that the Traffic-Control Index TCINDEX implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-1281 It was discovered that the KVM VMX...

USN-5976-1 linux-oem-5.14, linux-oem-5.17 vulnerabilities

It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...

USN-5970-1: Linux kernel vulnerabilities

It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. CVE-2022-2196 It was discovered...

DEBIAN-CVE-2023-1513

A flaw was found in KVM. When calling the KVMGETDEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvmdebugregs structure that could be copied to userspace, causing an information leak...

Important: kernel

Issue Overview: A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L...

UBUNTU-CVE-2022-42332

x86 shadow plus log-dirty mode use-after-free In environments where host assisted address translation is necessary but Hardware Assisted Paging HAP is unavailable, Xen will run guests in so called shadow mode. Shadow mode maintains a pool of memory used for both shadow page tables as well as...
