CVE intelligence and bounded remediation

CVE-2019-16508 — Google Chrome Os security vulnerability

High CVSS 9.3

The Imagination Technologies driver for Chrome OS before R74-11895.B, R75 before R75-12105.B, and R76 before R76-12208.0.0 allows attackers to trigger an Integer Overflow and gain privileges via a malicious application. This occurs because of intentional access for the GPU process to /dev/dri/card1 and the PowerVR ioctl handler, as demonstrated by PVRSRVBridgeSyncPrimOpCreate.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
