Researchers Uncover First Native Spectre v2 Exploit Against Linux Kernel

Cybersecurity researchers have disclosed what they say is the "first native Spectre v2 exploit" against the Linux kernel on Intel systems that could be exploited to read sensitive data from the memory. The exploit, called Native Branch History Injection BHI, can be used to leak arbitrary kernel...

CVE-2024-2201

A flaw was found in some Intel CPUs where mitigations for the Spectre V2/BHI vulnerability were incomplete. This issue may allow an attacker to read arbitrary memory, compromising system integrity and exposing sensitive information. Mitigation Mitigation for this issue is either not available or...

x86: Native Branch History Injection

ISSUE DESCRIPTION In August 2022, researchers at VU Amsterdam disclosed Spectre-BHB. Spectre-BHB was discussed in XSA-398. At the time, the susceptibility of Xen to Spectre-BHB was uncertain so no specific action was taken in XSA-398. However, various changes were made thereafter in upstream Xen ...
