CVE-2019-18567Public exploit

Kernel-data disclosure or crash via raced buffer read

Published Feb 3, 2020 · Updated Sep 16, 2024

Out-of-bounds read in Bromium Secure Client before 4.1.7 Update 1 allows local users to expose kernel data or crash the host. A race in an undisclosed host-kernel component lets concurrent state changes drive a read past its intended memory boundary. Local unprivileged access is required; the result is limited to kernel-data disclosure or a machine crash, with no VM escape.
