CVE-2024-42240

CVE-2024-42240: Linux kernel x86/bhi vulnerability where, when BHI mitigation is enabled, an entry_SYSENTER_compat() sequence could trigger a #DB handler warning due to the TF single-step bit handling. The fix changes the order to clear the TF flag before or after clearing branch history as appro...

CVE-2024-42240 x86/bhi: Avoid warning in #DB handler due to BHI mitigation

In the Linux kernel, the following vulnerability has been resolved: x86/bhi: Avoid warning in DB handler due to BHI mitigation When BHI mitigation is enabled, if SYSENTER is invoked with the TF flag set then entrySYSENTERcompat uses CLEARBRANCHHISTORY and calls the clearbhbloop before the TF flag...

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...

Linux kernel on Intel systems is susceptible to Spectre v2 attacks

Overview A new cross-privilege Spectre v2 vulnerability that impacts modern CPU architectures supporting speculative execution has been discovered. CPU hardware utilizing speculative execution that are vulnerable to Spectre v2 branch history injection BHI are likely affected. An unauthenticated...
