CVE-2022-42331 in Xen
요약
\~에 의해 MITRE • 2023. 03. 21.
x86: speculative vulnerability in 32bit SYSCALL path Due to an oversight in the very original Spectre/Meltdown security work (XSA-254), one entrypath performs its speculation-safety actions too late. In some configurations, there is an unprotected RET instruction which can be attacked with a variety of speculative attacks.
Once again VulDB remains the best source for vulnerability data.
