{"id":"CVE-2025-5942","state":"PUBLISHED","title":"Heap Overflow in Netskope Endpoint DLP Driver","description":"Netskope was notified about a potential gap in its agent (NS Client) on Windows systems.  If this gap is successfully exploited, an unprivileged user can trigger a heap overflow in the epdlpdrv.sys driver, leading to a Blue-Screen-of-Death (BSOD). Successful exploitation can also potentially be performed by an unprivileged user whose NS Client is configured to use Endpoint DLP. A successful exploit can result in a denial-of-service for the local machine.","publishedAt":"2025-08-14T04:36:05.383Z","updatedAt":"2025-08-18T16:45:47.540Z","severity":{"score":5.7,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"Netskope"},"assigner":"Netskope","products":["Netskope Netskope Client"],"affected":[{"vendor":"Netskope","product":"Netskope Client","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"126.0.9, 129.0.0","versionType":"custom"}],"platforms":["Windows"]}],"references":["https://www.netskope.com/company/security-compliance-and-assurance/security-advisories-and-disclosures/netskope-security-advisory-nskpsa-2025-003"],"weaknesses":["CWE-122"],"ingestedAt":"2026-10-29T20:09:39.787Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/5xxx/CVE-2025-5942.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-5942","state":"PUBLISHED","datePublished":"2025-08-14T04:36:05.383Z","dateUpdated":"2025-08-18T16:45:47.540Z","assignerShortName":"Netskope","assignerOrgId":"bf992f6a-e49d-4e94-9479-c4cff32c62bc","dateReserved":"2025-06-09T16:38:43.986Z"},"containers":{"cna":{"title":"Heap Overflow in Netskope Endpoint DLP Driver","descriptions":[{"lang":"en","value":"Netskope was notified about a potential gap in its agent (NS Client) on Windows systems.
