CVE-2026-115231 is a high-severity flaw (CVSS 8.5) affecting eclipse threadx. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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

eclipse foundation eclipse threadx UPGRADE

Affected: >= 6.0.1 and <= 6.5.2.202603

Fixed in: newer than 6.5.2.202603

Safe to downgrade to: a release before 6.0.1

1. Check installed version

apt-cache policy eclipse-threadx || rpm -q eclipse-threadx || eclipse-threadx --version

2. UPGRADE to newer than 6.5.2.202603 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade eclipse-threadx

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade eclipse-threadx

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.0.1 (Debian / Ubuntu)

apt-cache madison eclipse-threadx sudo apt install eclipse-threadx=<VERSION_BEFORE_6.0.1> sudo apt-mark hold eclipse-threadx

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list eclipse-threadx sudo dnf downgrade eclipse-threadx-<VERSION_BEFORE_6.0.1> sudo dnf versionlock add eclipse-threadx

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
