kernel: Kernel: Information disclosure via shared microarchitectural predictor state in Intel(R) Processors

Exposure of sensitive information caused by shared microarchitectural predictor state that influences transient execution for some Intel(R) Processors within VMX non-root (guest) operation may allow an information disclosure. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (none) and availability (none) impacts.

NVIDIA Jetson Linux contains a vulnerability in the kernel where an attacker may cause an exposure of sensitive information due to a shared microarchitectural predictor state that influences transient execution. A successful exploit of this vulnerability may lead to information disclosure.

microcode_ctl: Exposure of sensitive information

Exposure of sensitive information caused by shared microarchitectural predictor state that influences transient execution for some Intel(R) Core™ processors (10th Generation) may allow an authenticated user to potentially enable information disclosure via local access.

microcode_ctl: Exposure of sensitive information

Exposure of sensitive information caused by shared microarchitectural predictor state that influences transient execution in the indirect branch predictors for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

microcode_ctl: Exposure of sensitive information

Exposure of sensitive information caused by shared microarchitectural predictor state that influences transient execution for some Intel Atom(R) processors may allow an authenticated user to potentially enable information disclosure via local access.

CVE-2024-2201

A cross-privilege Spectre v2 vulnerability allows attackers to bypass all deployed mitigations, including the recent Fine(IBT), and to leak arbitrary Linux kernel memory on Intel systems.

Spectre-BSE

In certain circumstances, an issue in Arm Cortex-A57, Cortex-A72 (revisions before r1p0), Cortex-A73 and Cortex-A75 may allow an adversary to gain a weak form of control over the victim's branch history.
