CVE-2026-102805
MediumCVSS 6.5Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
A flaw was found in Nothings stb up to version 1.16 affecting the stbi_write_png_to_mem, stbi_write_jpg_core, and stbi_write_tga_core functions (stb_image_write.h) in the Image Encoding component. Manipulation leads to an integer overflow. The attack can be executed remotely, and the exploit is publicly available.
Risk Assessment
A remote attacker can exploit the integer overflow to cause application crashes or potentially achieve code execution. The public exploit increases the risk of exploitation in attacks.
Recommendation
Update the stb library to the latest version if a patch is available, or implement custom input validation before image encoding. Monitor systems for unusual behavior related to image processing.
