CVE-2025-15535Public exploit

Application crash via unchecked text-cache pointer

Published Jan 18, 2026 · Updated Jan 18, 2026

Null pointer dereference in Clay 0.14 and earlier allows local users to crash a host application through malformed text elements. Clay__MeasureTextCached reads a member through a null structure pointer without a validity check after Clay__OpenTextElement accepts crafted text-layout data. Exploitation requires low-privileged local access and interrupts only the application embedding the library.
