A use of uninitialized value vulnerability exists in the Matter SDK (connectedhomeip) before 1.4.0, where the `GetDestinationGroupId().Value()` method is called without first checking whether a value exists. This leads to a crash when an InvokeCommand is sent without initializing the destination group ID. The issue affects all versions before commit 0360cc3 (Dec 5, 2024) and leads to denial of service through SIGABRT. It is fixed by adding a .HasValue() check before access.
Security readout for executives and security teams
Plain-English summary
CVE-2025-56364 is a crash-level denial-of-service issue in the Matter SDK connectedhomeip before 1.4.0. A malformed command path can trigger a SIGABRT because code reads an optional destination group ID without checking whether it exists. The sources do not identify affected downstream products or active exploitation.
Executive priority
Treat as a high-priority availability risk for Matter-enabled environments, especially where uptime matters. The evidence supports crash-based disruption, not compromise of confidentiality or integrity. Business urgency depends on whether your products or vendors embed affected connectedhomeip versions.
Technical view
The flaw is CWE-457 use of an uninitialized value. In connectedhomeip before commit 0360cc3, GetDestinationGroupId().Value() is reached without a prior HasValue() check. The CVSS 3.1 score is 7.5: network exploitable, low complexity, no privileges, no user interaction, availability impact only.
Likely exposure
Exposure is most likely in systems built with Matter SDK connectedhomeip versions before 1.4.0 or before commit 0360cc3. The CVE source lists vendor and product as n/a, so downstream device exposure is not established in the provided evidence.
Exploitation context
The source bundle supports denial of service through a crash, not code execution or data theft. KEV status is false, and no provided source states active exploitation. The CVSS vector indicates network reachability without authentication or user interaction.
Researcher notes
The core issue is an unchecked optional access in InvokeCommand handling. The public description identifies a HasValue() guard as the fix. Source evidence is incomplete for downstream affected products, exploit maturity, and vendor-specific remediation timelines.
Mitigation direction
Upgrade connectedhomeip to 1.4.0 or a build containing commit 0360cc3.
Review project-chip issue and pull request guidance for the exact fixed code path.
Ask device or firmware vendors whether their products embed affected connectedhomeip code.
Prioritize updates for network-reachable Matter components.
Use vendor-supported backports if immediate full upgrade is impractical.
Validation and detection
Inventory software and firmware that embeds project-chip connectedhomeip.
Confirm connectedhomeip version is 1.4.0 or includes commit 0360cc3.
Review SBOMs and build metadata for affected Matter SDK revisions.
Check vendor advisories for downstream product-specific impact statements.
Monitor logs or crash telemetry for unexplained SIGABRT events in Matter services.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
