CVE-2026-8313
HighCVSS 7.3Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
A memory corruption vulnerability exists in Arena® Simulation within the linker.exe (Siman) component due to improper validation of user-supplied data, leading to an out-of-bounds write.
Risk Assessment
An attacker can exploit this vulnerability to execute arbitrary code in the context of the current process by convincing a user to open a malicious file, potentially leading to system compromise or data theft.
Recommendation
Update Arena® Simulation to the latest patched version immediately. Avoid opening files from untrusted sources.
