This is because segment registers with an arbitrary user value \ncan result in #GP when executing VERW. Intel SDM vol. 2C documents the \nfollowing behavior for VERW instruction: \n \n #GP(0) - If a memory operand effective address is outside the CS, DS, ES, \n FS, or GS segment limit. \n \nCLEAR_CPU_BUFFERS macro executes VERW instruction before returning to user \nspace. Use %cs selector to reference VERW operand. This ensures VERW will \nnot #GP for an arbitrary user %ds. \n \n[ mingo: Fixed the SOB chain. ] \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"29 Oct 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-10-29T03:03:14.000000Z"} 2024-10-29T03:03:14+00:00
