{"id":"CVE-2026-111380","summary":"FreeRDP 3.29.0 before 3.32.0 Heap Overflow via audin Apple Backends","details":"FreeRDP from 3.29.0 before 3.32.0 contains an integer overflow in the Apple audin backends (audin_mac.m, audin_ios.m), which compute the audio queue buffer size as FramesPerPacket * 2 * nChannels in UINT32 arithmetic, bypassing the CVE-2026-91962 fix. A malicious RDP server can send FramesPerPacket of 2^30 in the audin Open PDU to wrap the multiplication, causing undersized AudioQueueAllocateBuffer allocations and a heap out-of-bounds write in macOS and iOS clients.","aliases":["GHSA-72qv-gcph-rfwf"],"modified":"2026-10-17T02:48:18.806325005Z","published":"2026-10-16T01:17:48.329Z","database_specific":{"cwe_ids":["CWE-190"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111380.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111380.json"},{"type":"ADVISORY","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-72qv-gcph-rfwf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111380"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/freerdp-3.29.0-before-3.32.0-heap-overflow-via-audin-apple-backends"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freerdp/freerdp","events":[{"introduced":"743f437f434c6814d3ba265c75cab14673bc2911"},{"fixed":"d27a4f7c1c63b62a5e60e5d939ad116cfb58ffc1"}],"database_specific":{"extracted_events":[{"introduced":"3.29.0"},{"fixed":"3.32.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111380.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
