Versions on the 2.x branch prior to to 2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory by sending a crafted WIRE_TO_SURFACE_2 PDU with a `bitmapDataLength` value larger than the actual data in the packet. This can lead to information disclosure or client crashes when a user connects to a malicious server. Versions 2.11.8 and 3.23.0 fix the issue.","publishedAt":"2026-02-25T19:55:24.984Z","updatedAt":"2026-02-26T21:33:42.006Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["FreeRDP FreeRDP"],"affected":[{"vendor":"FreeRDP","product":"FreeRDP","versions":[{"version":">= 2.0.0, < 2.11.8","status":"affected"},{"version":">= 3.0.0, < 3.23.0","status":"affected"}]}],"references":["https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-3546-x645-5cf8","https://github.com/FreeRDP/FreeRDP/commit/2e3b77e28ac6a398897d28ba464dcc5dfab9c9e2"],"weaknesses":["CWE-20","CWE-125"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/25xxx/CVE-2026-25941.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-25941","state":"PUBLISHED","datePublished":"2026-02-25T19:55:24.984Z","dateUpdated":"2026-02-26T21:33:42.006Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-09T16:22:17.787Z"},"containers":{"cna":{"title":"FreeRDP: vuln_1_15_1 RDPGFX WIRE_TO_SURFACE_2 Out-of-Bounds Read","descriptions":[{"lang":"en","value":"FreeRDP is a free implementation of the Remote Desktop Protocol.
