CVE-2026-56208— AOMedia libaom 缓冲区错误漏洞

一分钟漏洞结论

影响对象
Red Hat Red Hat Enterprise Linux 10.0 Extended Update Support
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

AOMedia libaom是AOMedia组织开源的一个视频编码库。 AOMedia libaom存在缓冲区错误漏洞，该漏洞源于libaom的堆缓冲区溢出问题，即AV1编码器的Look-Ahead Processing (LAP)模式在g_lag_in_frames设置为1或更高时绕过首遍统计循环缓冲区环绕保护，导致在每帧编码后发生232字节越界写入，损坏相邻堆对象，攻击者可通过影响编码器配置造成拒绝服务或潜在代码执行。

Vulnerability Title
Libaom: libaom: heap buffer overflow in av1 encoder first-pass stats buffer via lap mode
来源: CVE Program / CVE List V5
Vulnerability Description
A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a denial of service (process crash) or potentially achieve code execution.
