Buffer Overflow vulnerability in Ardupiot Copter Latest commit 92693e023793133e49a035daf37c14433e484778 allows a local attacker to cause a denial of service via the AP_MSP::loop, AP_MSP, AP_MSP.cpp components.
Security readout for executives and security teams
Plain-English summary
CVE-2024-51394 is a reported buffer overflow in the AP_MSP area of Copter code tied to an ArduPilot repository issue. The CVSS score is 5.5 because exploitation is local, requires low privileges, and primarily affects availability. The business concern is denial of service on systems running affected builds, not confirmed data theft or remote compromise.
Executive priority
Treat as a moderate operational availability risk. Prioritize inventory and vendor tracking first, then patch once guidance is available. Escalate for safety-sensitive or mission-critical deployments.
Technical view
The CVE describes CWE-119 memory corruption in AP_MSP::loop, AP_MSP, and AP_MSP.cpp, reportedly at commit 92693e023793133e49a035daf37c14433e484778. The vector is AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H. The provided record does not name concrete affected product versions, CPEs, a patch, or a mitigation.
Likely exposure
Exposure is likely limited to environments running Copter code matching or derived from the referenced commit. The CVE affected-product fields are n/a, so scope cannot be reliably determined from the bundle alone.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. The CVSS vector indicates a local, low-privilege attacker could cause denial of service, with no stated confidentiality or integrity impact.
Researcher notes
Evidence is sparse: one CVE record and one GitHub issue reference are provided, with affected vendor/product/version fields set to n/a. Avoid broad product claims until upstream confirms scope and remediation details.
Mitigation direction
Check the referenced ArduPilot issue and vendor guidance for fixes or workarounds.
Inventory Copter builds matching or derived from the referenced commit.
Restrict local access to systems that can interact with the affected software.
Update affected deployments when an upstream fix or vendor release is confirmed.
Monitor for abnormal crashes or restarts in MSP-related workflows.
Validation and detection
Confirm whether deployed builds include AP_MSP, AP_MSP::loop, or AP_MSP.cpp.
Map deployed source revisions against commit 92693e023793133e49a035daf37c14433e484778.
Review the GitHub issue for maintainer confirmation and fix status.
Check operational logs for denial-of-service symptoms around MSP handling.
Document whether each deployment is affected, not affected, or unknown.

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.

Improper Restriction of Operations within the Bounds of a Memory Buffer
Improper Restriction of Operations within the Bounds of a Memory Buffer represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
