{"id":"CVE-2026-111380","aliases":["GHSA-72qv-gcph-rfwf"],"url":"https://o3.security/vulnerability/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.","published":"2026-10-16T01:17:48.329Z","modified":"2026-10-17T02:48:18.806325005Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-17T02:48:18.806325005Z"}}
