CVE-2026-58496 (GCVE-0-2026-58496)
Vulnerability from cvelistv5
Published

Severity ?
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N
CWE
Summary
Thor Vector Graphics (ThorVG) is a production-ready vector graphics engine. Prior to 1.0.7, the `SFNT/TTF` font loader's `SfntLoader::gen` function in `tvgSfntLoader.cpp` reads `data[0] through data[3]` to identify the font type without first checking that the input buffer contains at least four bytes. Loading an undersized font directly from memory through public APIs such as `tvg::Text::load` causes an out-of-bounds read. Loading through a file path using `mmap` can mask the read because of page alignment; the memory-loading API directly exposes it. Depending on memory layout, a malformed short font may crash the consuming application or disclose adjacent heap memory. This issue is fixed in version 1.0.7.

CWE
  • CWE-476 - NULL Pointer Dereference
Summary
Thor Vector Graphics (ThorVG) is a production-ready vector graphics engine. Prior to version 1.0.5, a null pointer dereference in SvgLoader::run() allows any caller that passes untrusted SVG data to Picture::load() to crash the process with a 6-byte payload. This issue has been patched in version 1.0.5.
