CVE-2026-94202 Eclipse Foundation CVE debrief

Who should care

Defenders responsible for Eclipse ThreadX deployments should assess exposure and prioritize verification of input validation and memory access controls. They should also review the CVE record and apply patches for affected versions of Eclipse ThreadX. Additionally, defenders should monitor system logs for potential exploitation attempts and assess the vulnerability's operational impacts on their organization.

Why it matters

The vulnerability in Eclipse ThreadX's block-pool create dispatcher requires verification of input validation and memory access controls. Defenders should prioritize patching affected versions and monitoring system logs.

• Verify input validation and memory access controls for Eclipse ThreadX modules
• Review and apply patches for affected versions of Eclipse ThreadX
• Monitor system logs for potential exploitation attempts
• Assess exposure and prioritize verification of module validation

Technical summary

The `_txm_module_manager_tx_block_pool_create_dispatch` function in Eclipse ThreadX performs an out-of-bounds read during validation of the module's extra-parameter array. This occurs because it validates only two of the four parameter words provided by the memory-protected module. The issue arises from the dispatcher's handling of the extra-parameter array, leading to potential exploitation. Defenders should prioritize verifying the module's input validation and memory access controls, reviewing the Eclipse ThreadX version and applying patches if available.

Defensive priority

Defenders should prioritize verifying the module's input validation and memory access controls, reviewing the Eclipse ThreadX version and applying patches if available.

Recommended defensive actions

• Verify the Eclipse ThreadX version and apply patches if available
• Review the module's input validation and memory access controls
• Monitor system logs for potential exploitation attempts
• Assess exposure and prioritize verification of module validation
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes
