Local availability interruption

Published Oct 8, 2024 · Updated Oct 8, 2024

Improper input validation in OpenHarmony 4.0.0 through 4.1.0 allows local users to interrupt LiteOS-A availability. OpenHarmony has not published the affected LiteOS-A interface or the validation operation that mishandles attacker-controlled input. Low-privileged local access is required, no user interaction is needed, and the disclosed consequence is limited to availability; crash versus hang is unspecified.
