CVE-2026-125213— FFmpeg through 9.0.2 Heap Buffer Overflow via PSD Decoder RLE Path

Quick assessment

Affected
FFmpeg FFmpeg
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 及更早版本中的 PSD 解码器（位于 libavcodec/psd.c）存在堆缓冲区溢出漏洞。攻击者可通过提供特制的 PSD 图像，在 32 位构建版本中破坏堆内存。攻击者可以指定图像尺寸和通道数，使其乘积超过 4 GB，从而导致 av_malloc 分配的内存大小被截断；这使得 decode_rle() 函数将攻击者控制的数据写入缓冲区之外，进而引发程序崩溃或可能导致代码执行。

Vulnerability Title
FFmpeg through 9.0.2 Heap Buffer Overflow via PSD Decoder RLE Path
Source: CVE Program / CVE List V5
Vulnerability Description
FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in the PSD decoder in libavcodec/psd.c that allows attackers to corrupt heap memory on 32-bit builds by supplying a crafted PSD image. Attackers can choose dimensions and channel counts whose product exceeds 4 GB, truncating the av_malloc allocation size so decode_rle() writes attacker-controlled data past the buffer, causing crashes or possible code execution.
