CVE-2026-126050 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
