An information disclosure vulnerability exists on ARM implementations that use speculative execution in control flow via a side-channel analysis, aka "straight-line speculation."
To exploit this vulnerability, an attacker with local privileges would need to run a specially crafted application.
The security update addresses the vulnerability by bypassing the speculative execution.
