CVE-2023-20593 – hw: amd: Cross-Process Information Leak
https://notcve.org/view.php?id=CVE-2023-20593
24 Jul 2023 — An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. A flaw was found in hw, in “Zen 2” CPUs. This issue may allow an attacker to access sensitive information under specific microarchitectural circumstances. Daniel Moghimi discovered that some Intel Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensiti... • https://github.com/sbaresearch/stop-zenbleed-win • CWE-209: Generation of Error Message Containing Sensitive Information CWE-1239: Improper Zeroization of Hardware Register •
