{"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":"2026-08-18T18:38:44.621209Z","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":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25941.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-125","CWE-20"]},"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"},{"introduced":"a34fa7c49d2a39aa49ace1d7bea9656912d8c7cb"},{"fixed":"b933ae18d9ad2a1d73c610868fcc30eb61654070"},{"fixed":"2e3b77e28ac6a398897d28ba464dcc5dfab9c9e2"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.11.8"},{"introduced":"3.0.0"},{"fixed":"3.23.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:freerdp:freerdp:*:*:*:*:*:*:*:*"}}],"versions":["2.11.7","3.5.1","2.11.6","3.5.0","3.4.0","3.3.0","3.2.0","2.11.5","3.1.0","2.11.4","2.11.3","3.0.0","2.11.2","2.11.1","2.11.0","2.10.0","2.9.0","2.8.1","2.8.0","2.7.0","2.6.1","2.6.0","2.5.0","2.4.1","2.3.2","2.3.1","2.3.0","2.2.0","2.1.2","2.1.1","2.1.0","2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-25941.json","vanir_signatures_modified":"2026-08-18T18:38:44Z","vanir_signatures":[{"id":"CVE-2026-25941-09968854","signature_type":"Function","signature_version":"v1","source":"https://github.com/freerdp/freerdp/commit/2e3b77e28ac6a398897d28ba464dcc5dfab9c9e2","target":{"file":"channels/rdpgfx/client/rdpgfx_main.c","function":"rdpgfx_recv_wire_to_surface_2_pdu"},"deprecated":false,"digest":{"function_hash":"87785624444684630625403399873965558033","length":1720}},{"signature_type":"Line","signature_version":"v1","source":"https://github.com/freerdp/freerdp/commit/2e3b77e28ac6a398897d28ba464dcc5dfab9c9e2","target":{"file":"channels/rdpgfx/client/rdpgfx_main.c"},"deprecated":false,"digest":{"line_hashes":["198606674677032849176492837790532723166","278568999666518782215971555724612607818","27072193264022785266947455296503428501","274262194524544336846558719596308508606"],"threshold":0.9},"id":"CVE-2026-25941-ff610600"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
