The MonitorIds array is allocated through the settings object, and a raw non-owning pointer to it is freed on the strtoul error path without clearing settings-\u003eMonitorIds, leaving it dangling; at teardown freerdp_settings_free() frees the same buffer again. An attacker who convinces a victim to open a crafted .rdp file with oversized monitor tokens can trigger a size-controlled double-free in any FreeRDP CLI client (xfreerdp/sdl-freerdp/wlfreerdp) in the default configuration.","severity":{"version":"4.0","score":9.3,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","level":"critical","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00363,"percentile":0.30516,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-415"],"published":"2026-07-20T12:04:53Z","modified":"2026-10-29T11:30:38Z","fixes":[{"ecosystem":"Debian:14","package":"freerdp3","fixed_in":["3.28.0+dfsg-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"freerdp3","fixed_in":["3.30.0+dfsg-0ubuntu0.24.04.1"],"sources":["osv"]},{"ecosystem":"Ubuntu:26.04:LTS","package":"freerdp3","fixed_in":["3.30.0+dfsg-0ubuntu0.26.04.1"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-server","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"AlmaLinux:10","package":"libwinpr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"AlmaLinux:10","package":"libwinpr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-12.el10_2.8"}]}],"bundled":6},{"source":"osv","ecosystem":"Debian:12","package":"freerdp2","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.0+dfsg1-1","2.10.0+dfsg1-1.1","2.11.2+dfsg1-1","2.11.2+dfsg1-1.1~exp1","2.11.2+dfsg1-1.1~exp2","2.11.5+dfsg1-1","2.11.7+dfsg1-1","2.11.7+dfsg1-2","2.11.7+dfsg1-3","2.11.7+dfsg1-4","2.11.7+dfsg1-5","2.11.7+dfsg1-6","2.11.7+dfsg1-6~deb12u1"]},{"source":"osv","ecosystem":"Debian:13","package":"freerdp3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.15.0+dfsg-2.1","3.15.0+dfsg-2.1+deb13u1","3.15.0+dfsg-2.1+deb13u2","3.15.0+dfsg-2.1+deb13u3","3.16.0+dfsg-1","3.16.0+dfsg-2","3.17.0+dfsg-1","3.17.1+dfsg-1","3.17.1+dfsg-2","3.17.2+dfsg-1","3.17.2+dfsg-2","3.17.2+dfsg-3","3.18.0+dfsg-1","3.19.0+dfsg-1","3.19.1+dfsg-1","3.20.0+dfsg-1","3.20.2+dfsg-1","3.21.0+dfsg-1","3.22.0+dfsg-1","3.22.0+dfsg-1~bpo13+0","3.22.0+dfsg-1~bpo13+1","3.22.0+dfsg-3","3.23.0+dfsg-1","3.23.0+dfsg-1~bpo13+1","3.24.0+dfsg-1","3.24.0+dfsg-2","3.24.1+dfsg-1","3.24.2+dfsg-1","3.24.2+dfsg-1~bpo13+1","3.25.0+dfsg-1","3.25.0+dfsg-2","3.25.0+dfsg-3","3.25.0+dfsg-4","3.25.0+dfsg-5","3.26.0+dfsg-1","3.26.0+dfsg-1~bpo13+1","3.27.0+dfsg-1","3.27.1+dfsg-1","3.28.0+dfsg-1","3.28.0+dfsg-2","3.29.0+dfsg-1","3.30.0+dfsg-1","3.30.0+dfsg-1~bpo13+1","3.31.0+dfsg-1","3.31.1+dfsg-1","3.31.1+dfsg-1~bpo13+1","3.32.0+dfsg-1","3.32.1+dfsg-1","3.32.1+dfsg-1~bpo13+1"]},{"source":"osv","ecosystem":"Debian:14","package":"freerdp3","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28.0+dfsg-1"}]}],"versions":["3.15.0+dfsg-2.1","3.16.0+dfsg-1","3.16.0+dfsg-2","3.17.0+dfsg-1","3.17.1+dfsg-1","3.17.1+dfsg-2","3.17.2+dfsg-1","3.17.2+dfsg-2","3.17.2+dfsg-3","3.18.0+dfsg-1","3.19.0+dfsg-1","3.19.1+dfsg-1","3.20.0+dfsg-1","3.20.2+dfsg-1","3.21.0+dfsg-1","3.22.0+dfsg-1","3.22.0+dfsg-1~bpo13+0","3.22.0+dfsg-1~bpo13+1","3.22.0+dfsg-3","3.23.0+dfsg-1","3.23.0+dfsg-1~bpo13+1","3.24.0+dfsg-1","3.24.0+dfsg-2","3.24.1+dfsg-1","3.24.2+dfsg-1","3.24.2+dfsg-1~bpo13+1","3.25.0+dfsg-1","3.25.0+dfsg-2","3.25.0+dfsg-3","3.25.0+dfsg-4","3.25.0+dfsg-5","3.26.0+dfsg-1","3.26.0+dfsg-1~bpo13+1","3.27.0+dfsg-1","3.27.1+dfsg-1"]},{"source":"osv","ecosystem":"Red
