Last modified Jun 17, 2026

CVE-2025-8854 is a high-severity vulnerability rated 8.4/10 on the CVSS scale. Stack-based buffer overflow in LoadOFF in bulletphysics bullet3 before 3.26 on all platforms allows remote attackers to execute arbitrary code via a crafted OFF file with an overlong initial token processed by the VHACD test utility or invoked indirectly through PyBullet's vhacd function.. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
