HIGHCVSS 8.5/10EPSS 0.11%

Last modified

CVE-2026-115231 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager lets a user-mode, memory-protected module post a forged callback request to another module's callback request queue. The receiving module's callback thread calls the function pointer in the request without checking that the Module Manager sent it, so the attacker's code runs with the receiving module's privilege; when that module runs in privileged mode, a user-mode module gains privileged execution.. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
