CVE-2026-6432
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk48th percentile - higher than 48% of all known CVEs
Summary
Improper bounds validation in the ZAP command parser of EmberZNet SDK versions 8.0.0 through 9.1.1 (inclusive) and before 7.5.2 (exclusive) may result in crashes or dynamic memory leakage. To exploit this vulnerability, an attacker would have to be able to send arbitrary messages on the network. The only known exploit leaks a limited number of bytes from the stack.
Risk Assessment
An attacker with network access can cause crashes or leak a limited amount of stack data, though no denial-of-service, memory corruption, or remote code execution has been demonstrated.
Recommendation
Upgrade EmberZNet SDK to version 7.5.2 or 9.1.2 (or later) and restrict the ability to send arbitrary network messages to trusted devices.
