{"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":"2026-05-18T05:58:38.183412659Z","published":"2026-02-25T19:55:24.984Z","related":["SUSE-SU-2026:1632-1","SUSE-SU-2026:1633-1","SUSE-SU-2026:1634-1","SUSE-SU-2026:1635-1","SUSE-SU-2026:1640-1","SUSE-SU-2026:21436-1","openSUSE-SU-2026:10408-1","openSUSE-SU-2026:10611-1","openSUSE-SU-2026:20632-1","openSUSE-SU-2026:20657-1"],"database_specific":{"cwe_ids":["CWE-125","CWE-20"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25941.json"},"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":"a34fa7c49d2a39aa49ace1d7bea9656912d8c7cb"},{"fixed":"b933ae18d9ad2a1d73c610868fcc30eb61654070"}]}],"versions":["3.5.1","3.5.0","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-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"}]}
