Easy way to run the script.Other operating systems such as MacOS, Windows, ESXi, etc. ), it also works if you've compiled your own kernel. FreeBSD, NetBSD, DragonFlyBSD and derivatives (others BSDs are not supported)įor Linux systems, the tool will detect mitigations, including backported non-vanilla patches, regardless of the advertised kernel version number and the distribution (such as Debian, Ubuntu, CentOS, RHEL, Fedora, openSUSE, Arch.Linux (all versions, flavors and distros).Machine Check Exception on Page Size Changes Microarchitectural Data Sampling Uncacheable Memory Microarchitectural Load Port Data Sampling Microarchitectural Fill Buffer Data Sampling Microarchitectural Store Buffer Data Sampling *cpe:2.3:o:xen:xen:*:*:*:*:*:*:x86:* versions from (including) 4.5.0 up to (including) 4.17.A shell script to assess your system's resilience against the several transient execution CVEs that were published since early 2018, and give you guidance as to how to mitigate them. Initial Analysis by NIST 10:10:23 AM Action Please address comments about this page to List Third Party Advisory Further, NIST does notĮndorse any commercial products that may be mentioned on Not necessarily endorse the views expressed, or concur with As a standalone vulnerability, Spectre and Meltdown are fairly inefficient for mass data exfiltration, as initial research demonstrates Meltdown is able to access data at about 120 KB/s, with. Sites that are more appropriate for your purpose. Inferences should be drawn on account of other sites being VMware has issued a VMware Security Advisory (VMSA) covering. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. Note the following official statement from VMware regarding the new Retbleed vulnerability addressed in VMSA-2022-0020: On July 12, 2022, several CPU manufacturers, along with security researchers, announced security advisories addressing side-channel vulnerabilities in CPU hardware. Meltdown and Spectre exploit critical vulnerabilities in modern processors. May have information that would be of interest to you. 'The Spectre vulnerability that has haunted hardware and software makers since 2018 continues to defy efforts to bury it,' reports the Register: On Thursday, Eduardo (sirdarckcat) Vela Nava, from Googles product security response team, disclosed a Spectre-related flaw in version 6.2 of the Linux kernel. Meltdown and Spectre are vulnerabilities in modern computers that can be used to leak passwords and sensitive data.
