CVE-2026-126050

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.
