CVE-2020-1459

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2020-1459
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.
