[GHSA-mh75-5pr3-qv2p: NetRx: out-of-bounds read via unvalidated MsgAudio length]

AnalysisAI

Out-of-bounds read in NetRx's audio message handling exposes memory contents and may cause service disruption when processing crafted MsgAudio payloads with unvalidated length fields. The affected component fails to validate the length field of incoming MsgAudio messages before using it to index or copy memory, a classic CWE-125-class flaw. …

Execution
Trigger out-of-bounds read in NetRx
Impact
Leak adjacent memory or crash service

Vulnerability AssessmentAI

Exploitation The NetRx component must be running and reachable by the attacker - either directly over the network (if it accepts remote audio messages) or locally (if it processes inter-process audio messages). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Formal risk signals are almost entirely absent for this CVE: no CVSS score or vector, no CWE assignment, no EPSS probability, no KEV listing, no POC or exploit code reported, and no patch version confirmed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker sends a crafted network message with a malformed or oversized MsgAudio length field to the NetRx listener. The component reads beyond the intended buffer boundary, either leaking adjacent memory contents (potentially exposing sensitive data such as keys or session tokens) or causing a null-dereference or segmentation fault that crashes the service. …
Remediation No vendor-released patch or specific fix version has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
