Thread Priority Manipulation in Eclipse ThreadX by Eclipse

CVE-2025-55079

What is CVE-2025-55079?

A vulnerability exists in Eclipse ThreadX prior to version 6.4.3, where the thread module fails to properly enforce its maximum priority setting. This oversight can allow an attacker to gain unauthorized access to a thread operating at a higher priority than intended, potentially leading to a denial of service condition. By exploiting this flaw, malicious entities may disrupt the normal functioning of applications relying on Eclipse ThreadX.
