CVE-2018-14855 — Samsung Galaxy S6 Firmware security vulnerability

Medium CVSS 6.3

Buffer overflow in dhd_bus_flow_ring_flush_response in drivers/net/wireless/bcmdhd4358/dhd_pcie.c in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 allow an attacker (who has obtained code execution on the Wi-Fi chip) to cause the device driver to perform invalid memory accesses. The Samsung ID is SVE-2018-11785.

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.
