CVE-2026-126050— apitrace 2.0 through 14.0 Heap Buffer Overflow via SnappyFile::flushReadCache()

Quick assessment

Affected
apitrace apitrace
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.

apitrace 2.0 至 14.0 版本中，SnappyFile::flushReadCache() 函数存在基于堆的缓冲区溢出漏洞。攻击者可利用过大的压缩块长度，将数据写入 m_compressedCache 缓冲区之外。攻击者可以构造一个 .trace 文件，使其 4 字节的块长度超过固定缓冲区大小；当用户对该文件进行转储、检查或回放时，将导致堆内存被破坏。

Vulnerability Title
apitrace 2.0 through 14.0 Heap Buffer Overflow via SnappyFile::flushReadCache()
Source: CVE Program / CVE List V5
Vulnerability Description
apitrace 2.0 through 14.0 contains a heap-based buffer overflow in SnappyFile::flushReadCache() that allows attackers to write past m_compressedCache via an oversized compressed chunk length. Attackers can supply a crafted .trace file whose 4-byte chunk length exceeds the fixed buffer size, corrupting heap memory when users dump, inspect, or replay it.
