CVE-2021-32025

Privilege escalation via kernel context-switching race

Published Mar 9, 2022 · Updated Aug 22, 2025

Privilege escalation in affected BlackBerry QNX products allows local users to access data, modify behavior, or permanently crash systems. BlackBerry identifies a context-switching race in the QNX Neutrino Kernel but has not disclosed the raced operation or affected kernel path. Exploitation requires local code execution and a high-complexity race; success can cross a security boundary and permanently interrupt the device.
