CVE-2018-9567

Status: ModifiedHigh (7.8)—
Severity7.8High · CVSS 3.0
Exploitation probability0.15 %higher than 3% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

On Pixel devices there is a bug causing verified boot to show the same certificate fingerprint despite using different signing keys. This may lead to local escalation of privilege if people are relying on those fingerprints to determine what version of the OS the device is running, with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-65543936.
