{"id":"CVE-2024-12668","state":"PUBLISHED","title":"Velocidex WinPmem Out of Bounds Write Vulnerability","description":"Velocidex WinPmem versions below 4.1 suffer from an Out of Bounds Write vulnerability. By using an IO Control, a user space program can trick the driver into writing a 0 into any chosen memory location. In conjunction with information leakage from the WinPmem driver, attackers can discover the location in memory for the  g_CiOptions global symbol. This can be leveraged to disable signed driver enforcement on the target system - allowing attackers to load unsigned drivers.","publishedAt":"2024-12-16T14:56:17.136Z","updatedAt":"2024-12-16T16:14:22.987Z","severity":{"score":8.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","source":"rapid7"},"assigner":"rapid7","products":["Velocidex WinPmem"],"affected":[{"vendor":"Velocidex","product":"WinPmem","defaultStatus":"unaffected","versions":[{"version":"<= 4.1","status":"affected","versionType":"semver"}]}],"references":["https://github.com/Velocidex/WinPmem/releases/tag/v4.1.dev1"],"weaknesses":["CWE-787"],"ingestedAt":"2026-10-29T20:06:50.777Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/12xxx/CVE-2024-12668.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-12668","state":"PUBLISHED","datePublished":"2024-12-16T14:56:17.136Z","dateUpdated":"2024-12-16T16:14:22.987Z","assignerShortName":"rapid7","assignerOrgId":"9974b330-7714-4307-a722-5648477acda7","dateReserved":"2024-12-16T10:01:23.823Z"},"containers":{"cna":{"title":"Velocidex WinPmem Out of Bounds Write Vulnerability","descriptions":[{"lang":"en","value":"Velocidex WinPmem versions below 4.1 suffer from an Out of Bounds Write vulnerability. By using an IO Control, a user space program can trick the driver into writing a 0 into any chosen memory location.
