UBUNTU-CVE-2020-10766

A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced...

CVE-2020-13844

CVE-2020-13844 relates to Arm Armv8-A core implementations where speculative execution past unconditional changes in control flow can lead to information disclosure via a side-channel (straight-line speculation). The impact is information disclosure with local access; no remote vector is describe...

New Noise-Resilient Attack On Intel and AMD CPUs Makes Flush-based Attacks Effective

Modern Intel and AMD processors are susceptible to a new form of side-channel attack that makes flush-based cache attacks resilient to system noise, newly published research shared with The Hacker News has revealed. The findings are from a paper "DABANGG: Time for Fearless Flush based Cache...

CVE-2020-0955

An information disclosure vulnerability exists when certain central processing units CPU speculatively access memory, aka 'Windows Kernel Information Disclosure in CPU Memory Access'...

CVE-2018-3693

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an...
