CVE-2024-2452Network attack vector

Heap corruption via wrapped aligned allocation size

Published Mar 26, 2024 · Updated Feb 13, 2025

Heap buffer overflow in Eclipse ThreadX NetX Duo before 6.4.0 allows remote attackers to corrupt heap memory via allocator parameters. The __portable_aligned_alloc() function computes an allocation size from attacker-controlled size or alignment values without rejecting integer wraparound, causing malloc() to reserve too little memory. The path requires no privileges or user interaction but has high complexity, and resulting heap corruption affects stored data and service operation.
