CVE-2021-29155

This is the Proof Of Concept code for CVE-2021-29155. The range tracking system for pointer arithmetic in the speculative domain was insufficient. It was possible to extract kernel data via a sidechannel. This is a proof of concept you can read up to 0x5fff bytes out of bounds from the last eleme...

exploit-cve-2017-5715

Spectre attack Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications...

Astra Linux – Vulnerability in Xen

Potential speculative code storage bypasses exist in all supported CPU products. Combined with software vulnerabilities related to speculative execution of overwritten instructions, this could lead to incorrect speculation and potentially cause data leakage...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: using arrayindexnospec with indices that come from the guest min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks helps to mitigate speculative execution side-channels by clamping...
