Security readout for executives and security teams
Plain-English summary
This CVE affects Intel SGX Platform Software for Linux before 2.1.102. A local attacker could effectively disable the AESM daemon, disrupting SGX services such as remote attestation. The main business impact is loss of trust-verification capability for SGX-backed workloads, not evidence of remote takeover.
Executive priority
Treat this as a targeted reliability and trust-assurance issue for SGX environments. Prioritize remediation where SGX remote attestation protects sensitive workloads, confidential computing, or customer trust guarantees. Broad enterprise urgency is lower unless SGX is deployed.
Technical view
The issue is a local denial-of-service condition in the AESM daemon within Intel Software Guard Extensions Platform Software Component for Linux before 2.1.102. The CVE description specifically cites disruption to remote attestation provided by AESM. No CVSS vector, CWE, or detailed exploit mechanics are provided in the source bundle.
Likely exposure
Exposure is likely limited to Linux systems running Intel SGX Platform Software Component versions before 2.1.102, especially where AESM supports remote attestation workflows. Systems without SGX PSW or without reliance on AESM remote attestation are less directly exposed.
Exploitation context
The source describes a local attacker, so exploitation appears to require local access to the affected Linux system. The source bundle does not report active exploitation, public exploit availability, or inclusion in CISA KEV.
Researcher notes
Evidence is sparse: the bundle provides the affected component, pre-2.1.102 version boundary, local attacker requirement, and AESM denial-of-service impact. It does not provide CVSS, CWE, root cause details, exploit status, or operational indicators.
Mitigation direction
- Identify Linux hosts running Intel SGX Platform Software Component.
- Upgrade affected SGX Platform Software to version 2.1.102 or later.
- Check Intel guidance for any additional vendor-specific remediation.
- Limit local user access on SGX-enabled systems.
- Monitor AESM daemon health where remote attestation is business-critical.
Validation and detection
- Check installed SGX Platform Software version against 2.1.102.
- Confirm whether AESM is installed and running on SGX-enabled hosts.
- Identify services that depend on AESM remote attestation.
- Review local account access to affected Linux systems.
- Validate attestation-dependent workflows after remediation.
