{"id":"UBUNTU-CVE-2025-34449","details":"Genymobile/scrcpy versions up to and including 3.3.3, prior to commit 3e40b24, contain a buffer overflow vulnerability in the sc_device_msg_deserialize() function. A compromised device can send crafted messages that cause out-of-bounds reads, which may result in memory corruption or a denial-of-service condition. This vulnerability may allow further exploitation on the host system.","modified":"2026-05-20T16:21:24.006022123Z","published":"2025-12-18T22:15:00Z","upstream":["CVE-2025-34449"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-34449"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-34449"},{"type":"REPORT","url":"https://github.com/Genymobile/scrcpy/commit/3e40b24"},{"type":"REPORT","url":"https://github.com/Genymobile/scrcpy/issues/6415"},{"type":"REPORT","url":"https://github.com/marlinkcyber/advisories/blob/main/advisories/MCSAID-2025-003-scrcpy-global-buffer-overflow.md"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/genymobile-scrcpy-global-buffer-overflow"}],"affected":[{"package":{"name":"scrcpy","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/scrcpy?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.1+ds-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.12.1+ds-1","binary_name":"scrcpy"},{"binary_name":"scrcpy-server","binary_version":"1.12.1+ds-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34449.json"}},{"package":{"name":"scrcpy","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/scrcpy?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.17-1","1.19-1","1.21-1"],"ecosystem_specific":{"binaries":[{"binary_name":"scrcpy","binary_version":"1.21-1"},{"binary_version":"1.21-1","binary_name":"scrcpy-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34449.json"}},{"package":{"name":"scrcpy","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/scrcpy?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.25-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"scrcpy","binary_version":"1.25-1ubuntu1"},{"binary_name":"scrcpy-server","binary_version":"1.25-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34449.json"}},{"package":{"name":"scrcpy","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/scrcpy?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.25-1.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.25-1.1","binary_name":"scrcpy"},{"binary_name":"scrcpy-server","binary_version":"1.25-1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34449.json"}},{"package":{"name":"scrcpy","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/scrcpy?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.25-1.1","3.3.2-1","3.3.4-1"],"ecosystem_specific":{"binaries":[{"binary_name":"scrcpy","binary_version":"3.3.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-34449.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
