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 8.1 至 9.0.2 版本在中存在一个拒绝服务（DoS）漏洞：当 Vulkan 硬件加速回调失败时，仍被保留分配。攻击者可构造特制的 DPX 图像，致使、或函数执行失败，进而在处理下一帧时触发断言失败，导致解码应用程序终止。

Vulnerability Title

FFmpeg 8.1 through 9.0.2 Denial of Service via DPX Vulkan Hwaccel Error Path

Source: CVE Program / CVE List V5

Vulnerability Description

FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in libavcodec/dpx.c that leaves dpx->hwaccel_picture_private allocated when Vulkan hwaccel callbacks fail. Attackers can supply crafted DPX images that make start_frame, decode_slice or end_frame fail, triggering an av_assert0 abort on the next frame and terminating the decoding application.
