CVE-2026-0648
7.8 · HIGHOverview
CVE-2026-0648 is a high-severity vulnerability affecting eclipse threadx. It was published on January 27, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
The vulnerability stems from an incorrect error-checking logic in the CreateCounter() function (in threadx/utility/rtos_compatibility_layers/OSEK/tx_osek.c) when handling the return value of osek_get_counter(). Specifically, the current code checks if cntr_id equals 0u to determine failure, but @osek_get_counter() actually returns E_OS_SYS_STACK (defined as 12U) when it fails. This mismatch causes the error branch to never execute even when the counter pool is exhausted.
As a result, when the counter pool is depleted, the code proceeds to cast the error code (12U) to a pointer (OSEK_COUNTER *), creating a wild pointer. Subsequent writes to members of this pointer lead to writes to illegal memory addresses (e.g., 0x0000000C), which can trigger immediate HardFaults or silent memory corruption.
This vulnerability poses significant risks, including potential denial-of-service attacks (via repeated calls to exhaust the counter pool) and unauthorized memory access.
Remediation
Check the references section for vendor advisories and patches from eclipse. Update threadx to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
