{"id":"CVE-2026-15710","state":"PUBLISHED","title":"Netskope Client Endpoint DLP Kernel Driver Information Leakage","description":"An information leakage vulnerability exists in the Endpoint DLP component (epdlpdrv.sys) of Netskope Client for Windows prior to version R141. An internal communication channel used by the user-space hook DLL to pass messages through the kernel driver to the daemon lacked proper token-based message validation, allowing local unprivileged processes to send unauthorized queries. Additionally, a reply buffer used by the port message handler was not properly initialized before returning data, leaking residual kernel pool memory from prior allocations. A local unprivileged attacker could exploit this vulnerability to enumerate DLP configuration and feature flags, extract live session tokens, and read kernel memory fragments from other users' operations.","publishedAt":"2026-09-11T13:57:02.512Z","updatedAt":"2026-09-11T14:57:03.107Z","severity":{"score":6.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N","source":"Netskope"},"assigner":"Netskope","products":["Netskope Endpoint DLP"],"affected":[{"vendor":"Netskope","product":"Endpoint DLP","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"R141","versionType":"custom"}],"platforms":["Windows"]}],"references":["https://www.netskope.com/resources/netskope-resources/netskope-security-advisory-nskpsa-2026-006"],"weaknesses":["CWE-908"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15710.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15710","state":"PUBLISHED","datePublished":"2026-09-11T13:57:02.512Z","dateUpdated":"2026-09-11T14:57:03.107Z","assignerShortName":"Netskope","assignerOrgId":"bf992f6a-e49d-4e94-9479-c4cff32c62bc","dateReserved":"2026-07-14T09:39:25.451Z"},"containers":{"cna":{"title":"Netskope Client Endpoint DLP Kernel Driver Information Leakage","descriptions":[{"lang":"en","value":"An information leakage vulnerability exists in the Endpoint DLP component (epdlpdrv.sys) of Netskope Client for Windows prior to version R141.
