CVE-2024-39775
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedin OpenHarmony v4.1.0 and prior versions allow a remote attacker cause information leak through out-of-bounds Read.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpenHarmony v4.1.0 and prior versions contain an out-of-bounds read vulnerability that allows a remote attacker to read sensitive information from memory beyond allocated buffers. This information disclosure flaw could expose heap or stack data depending on the affected component's memory layout.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed OpenHarmony versionRun 'syscap' or check /etc/version on the device to determine the exact OpenHarmony release versionAffected if The installed version is 4.0.x or 4.1.0 (any patch level within 4.0-4.1 range)
-
Determine if network services are exposedReview network listener configurations and check which services are bound to accessible network interfaces using 'netstat -tuln' or similar network diagnostic toolsAffected if Any OpenHarmony network services handling data parsing are exposed to untrusted network paths
-
Identify components processing external dataAudit running processes and identify services that handle remote input, particularly those involved in protocol parsing, file handling, or inter-process communicationAffected if Components that process untrusted input are running and accessible
-
Review memory allocation patternsExamine logs or crash dumps for any out-of-bounds memory access errors, heap corruption indicators, or unexpected memory reads in system logsAffected if Logs contain memory access violations, unexpected read errors, or indications of buffer overruns in OpenHarmony components
The environment is affected if the installed OpenHarmony version falls within the 4.0 to 4.1 range AND network-accessible services process external input, as the vulnerability allows reading beyond allocated buffers in such configurations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-provided security update for OpenHarmony to the affected devices. If a patch is unavailable, restrict network exposure of vulnerable services and monitor for indicators of exploitation.
