Security readout for executives and security teams
Plain-English summary
OP-TEE 3.3.0 and earlier has a buffer overflow in optee_os. The stated impact is code execution in the TEE core kernel context, which is highly sensitive. The provided sources name version 3.4.0 and later as fixed, but do not provide CVSS, affected downstream products, or active exploitation evidence.
Executive priority
Prioritize as high where OP-TEE is present because the stated impact reaches TEE core kernel code execution. Business urgency depends on whether your products or suppliers include vulnerable OP-TEE versions, which the public CVE data does not enumerate.
Technical view
CVE-2019-1010298 is described as a buffer overflow in Linaro/OP-TEE optee_os affecting OP-TEE 3.3.0 and earlier. The CVE states potential code execution in the TEE core kernel context and identifies 3.4.0 and later as fixed. The source bundle does not include a CWE, CVSS vector, prerequisites, or attack-path detail.
Likely exposure
Exposure is likely limited to systems, firmware, or products that include Linaro/OP-TEE 3.3.0 or earlier. The sources do not identify downstream vendors, device models, distributions, or cloud services, so confirmation requires asset, firmware, and SBOM review.
Exploitation context
The source bundle does not cite CISA KEV listing or any public report of active exploitation. It also does not provide exploit prerequisites, privilege requirements, or reachable interfaces. Treat exploitation status as unconfirmed, while recognizing the stated TEE core code-execution impact.
Researcher notes
The evidence is sparse: CVE metadata names the vulnerable component, affected versions, impact, and fixed version, plus one upstream commit reference. It does not include CVSS, CWE, exploitability conditions, affected downstream products, or operational indicators. Avoid assuming internet exposure or exploitation without vendor-specific evidence.
Mitigation direction
- Upgrade OP-TEE to version 3.4.0 or later where applicable.
- Check OP-TEE and device vendor guidance for backports or platform-specific advisories.
- Inventory firmware and SBOMs for bundled OP-TEE versions.
- Prioritize remediation for products handling secrets or trusted execution workloads.
Validation and detection
- Confirm deployed OP-TEE version is newer than 3.3.0.
- Review firmware manifests, SBOMs, or vendor release notes for optee_os versions.
- Verify vendor firmware updates include the referenced OP-TEE fix or later release.
- Document systems where OP-TEE version cannot be determined.
