CVE-2026-96582 Eclipse Foundation CVE debrief
A HID peripheral returning a short report descriptor drove a heap out-of-bounds read during ordinary enumeration in Eclipse ThreadX - USBX versions 6.5.1.202602 and earlier. This issue was addressed in version 6.5.2.202603. The vulnerability arises from the USBX host walking a HID report descriptor sequence by advancing over each header and parsing the data behind it, but only checking that an item fitted in the descriptor after advancing past the header and parsing the payload. Defenders should assess exposure and prioritize upgrading to version 6.5.2.202603 or later.

Who should care
Defenders responsible for Eclipse ThreadX - USBX deployments should assess exposure and prioritize upgrading to version 6.5.2.202603 or later. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify inventory and ensure that affected systems are upgraded to the patched version.
Why it matters
Defenders should care about CVE-2026-96582 because it affects Eclipse ThreadX - USBX versions 6.5.1.202602 and earlier, potentially leading to a heap out-of-bounds read during ordinary enumeration. The issue was addressed in version 6.5.2.202603, and defenders should prioritize verifying inventory and upgrading to this version or later.
- Potential heap out-of-bounds read during enumeration
- Possible exposure of sensitive information
- Need for verification of inventory and upgrade to patched version
Technical summary
The USBX host walks a HID report descriptor sequence by advancing over each header and parsing the data behind it. However, the walk checked that an item fitted in the descriptor only after it had advanced past the header and parsed the payload. This led to a heap out-of-bounds read during ordinary enumeration. The issue was addressed in version 6.5.2.202603. Defenders should prioritize verifying inventory and upgrading to this version or later. The vulnerability affects Eclipse ThreadX - USBX versions 6.5.1.202602 and earlier.
Defensive priority
Defenders should prioritize verifying inventory and upgrading to version 6.5.2.202603 or later.
Recommended defensive actions
- Verify inventory of Eclipse ThreadX - USBX versions
- Upgrade to version 6.5.2.202603 or later
- Monitor for potential exploitation attempts
- 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
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
