CVE-2026-88368: n/a
NanoSVG contains a numeric conversion vulnerability in its rasterizer function nsvg__addActive(). Processing a specially crafted SVG with very large geometry coordinates can cause integer overflow during fixed-point scaling, leading to undefined behavior and potential process termination. This results in a denial of service condition.
AI Analysis
Technical Summary
CVE-2026-88368 describes a vulnerability in NanoSVG's rasterizer component, specifically in the nsvg__addActive() function. When an SVG document includes sufficiently large geometry coordinates, the fixed-point scaled edge coordinates can exceed the range of the int data type. The rasterizer converts these out-of-range values to int without validating the range, causing undefined behavior that may terminate the process and cause denial of service.
Potential Impact
An attacker can cause the NanoSVG rasterizer to crash or terminate unexpectedly by supplying a malicious SVG file with large coordinate values. This leads to denial of service by interrupting the normal operation of any application using the vulnerable NanoSVG version.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
