Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FFmpeg 9.0.2 及更早版本中存在堆缓冲区溢出漏洞。该漏洞位于 中的 函数，其问题在于将无限制的 PPS（图片参数集）图块（tile）数量复制到固定大小的 VDPAU 数组中。攻击者可构造包含过量图块列或行的 HEVC 比特流，从而将受控的 16 位值写入堆分配的硬件加速（hwaccel）数据之后，导致使用 VDPAU 解码的应用程序内存被破坏。

Vulnerability Title
FFmpeg through 9.0.2 Heap Buffer Overflow via HEVC VDPAU Tile Arrays
Source: CVE Program / CVE List V5
Vulnerability Description
FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in vdpau_hevc_start_frame() in libavcodec/vdpau_hevc.c that copies unbounded PPS tile counts into fixed-size VDPAU arrays. Attackers can supply crafted HEVC bitstreams with excessive tile columns or rows to write controlled 16-bit values past heap-allocated hwaccel data, corrupting memory in applications using VDPAU decoding.
