CVE-2026-88368

Integer Conversion Overflow Leading to Denial of Service in NanoSVG

Published Sep 24, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
NanoSVG commit 239e102ec contains an incorrect numeric conversion vulnerability in the rasterizer's nsvg__addActive() function. A specially crafted SVG document containing sufficiently large geometry coordinates can cause fixed-point-scaled edge coordinates to exceed the range representable by int. The rasterizer subsequently converts these values to int without range validation, resulting in undefined behavior and possible process termination, leading to denial of service.
