{"id":"CVE-2026-25941","summary":"FreeRDP: vuln_1_15_1 RDPGFX WIRE_TO_SURFACE_2 Out-of-Bounds Read","details":"FreeRDP is a free implementation of the Remote Desktop Protocol. 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.","aliases":["GHSA-3546-x645-5cf8"],"modified":"2026-04-02T13:18:55.516084Z","published":"2026-02-25T19:55:24.984Z","related":["openSUSE-SU-2026:10408-1"],"database_specific":{"cwe_ids":["CWE-125","CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25941.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25941.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-3546-x645-5cf8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25941"},{"type":"FIX","url":"https://github.com/FreeRDP/FreeRDP/commit/2e3b77e28ac6a398897d28ba464dcc5dfab9c9e2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"5ab2bed8749747b8e4b2ed431fd102bc726be684"},{"fixed":"9b678b6d5a40ce01607d8c3b1b1416437c8416c4"}],"database_specific":{"versions":[{"introduced":"2.0.0"},{"fixed":"2.11.8"}]}},{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"a34fa7c49d2a39aa49ace1d7bea9656912d8c7cb"},{"fixed":"b933ae18d9ad2a1d73c610868fcc30eb61654070"}],"database_specific":{"versions":[{"introduced":"3.0.0"},{"fixed":"3.23.0"}]}}],"versions":["2.0.0","2.1.0","2.1.1","2.1.2","2.10.0","2.11.0","2.11.1","2.11.2","2.11.3","2.11.4","2.11.5","2.11.6","2.11.7","2.2.0","2.3.0","2.3.1","2.3.2","2.4.1","2.5.0","2.6.0","2.6.1","2.7.0","2.8.0","2.8.1","2.9.0","3.0.0","3.0.0-beta1","3.0.0-beta2","3.0.0-beta3","3.0.0-beta4","3.0.0-rc0","3.1.0","3.10.0","3.10.1","3.10.2","3.10.3","3.11.0","3.11.1","3.12.0","3.13.0","3.14.0","3.14.1","3.15.0","3.16.0","3.17.0","3.17.1","3.17.2","3.18.0","3.19.0","3.19.1","3.2.0","3.20.0","3.20.1","3.20.2","3.21.0","3.22.0","3.23.0","3.24.0","3.24.1","3.3.0","3.4.0","3.5.0","3.5.1","3.6.0","3.6.1","3.6.2","3.6.3","3.7.0","3.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25941.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
