Integer Overflow
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

FreeRDP from 3.29.0 before 3.32.0 contains an integer overflow in the Apple audin backends (audinmac.m, audinios.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.

Double Free
AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing polygon order followed by a zero-point order to crash a client with +async-update enabled.
