CVE-2024-2212

Heap buffer overflow via unchecked queue-size multiplication

Published Mar 26, 2024 · Updated Feb 13, 2025

Heap buffer overflow in Eclipse ThreadX before 6.4.0 allows local users to overwrite heap memory via crafted queue parameters. The FreeRTOS compatibility functions xQueueCreate() and xQueueCreateSet() multiply attacker-controlled sizes without overflow checks, so txfr_malloc() allocates an undersized buffer. The calling application must pass attacker-controlled queue lengths or item sizes, after which subsequent queue use overwrites adjacent heap memory.
