CVE-2021-27411 (GCVE-0-2021-27411)
Vulnerability from cvelistv5 – Published: 2022-05-03 20:18 – Updated: 2025-04-16 16:25
VLAI?
Summary
Micrium OS Versions 5.10.1 and prior are vulnerable to integer wrap-around in functions Mem_DynPoolCreate, Mem_DynPoolCreateHW and Mem_PoolCreate. This unverified memory assignment can lead to arbitrary memory allocation, resulting in unexpected behavior such as very small blocks of memory being allocated instead of very large ones.
Severity ?
6.5 (Medium)

CVE-2021-26706 (GCVE-0-2021-26706)
Vulnerability from cvelistv5 – Published: 2022-01-24 00:19 – Updated: 2024-08-03 20:33
VLAI?
Summary
An issue was discovered in lib_mem.c in Micrium uC/OS uC/LIB 1.38.x and 1.39.00. The following memory allocation functions do not check for integer overflow when allocating a pool whose size exceeds the address space: Mem_PoolCreate, Mem_DynPoolCreate, and Mem_DynPoolCreateHW. Because these functions use multiplication to calculate the pool sizes, the operation may cause an integer overflow if the arguments are large enough. The resulting memory pool will be smaller than expected and may be exploited by an attacker.
Severity ?
No CVSS data available.
