Quick assessment
Affected
Red Hat Red Hat Enterprise Linux 10
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.
GStreamer是GStreamer组织开源的一个多媒体处理开发框架。 GStreamer存在缓冲区错误漏洞，该漏洞源于GStreamer gst-plugins-bad的adpcmdec元素在解码IMA/DVI ADPCM音频时对多声道流的每块样本数验证不足，特制的WAV文件可能导致超出分配输出缓冲区的写入，从而造成应用程序崩溃、拒绝服务、内存损坏或任意代码执行。

Vulnerability Title
Gstreamer: gstreamer1-plugins-bad-free: gstreamer: heap out-of-bounds write in adpcmdec ima/dvi adpcm decoder
Source: CVE Program / CVE List V5
Vulnerability Description
A heap out-of-bounds write vulnerability was found in the GStreamer gst-plugins-bad adpcmdec element when decoding IMA/DVI ADPCM audio. Insufficient validation of the per-block sample count for multi-channel streams allows a crafted WAV file to cause writes beyond the allocated output buffer. This can lead to application crash, denial of service, memory corruption, or potentially arbitrary code execution when untrusted media is processed.
