CVE intelligence and bounded remediation
CVE-2017-5538 — Samsung Samsung Mobile security vulnerability
Critical
CVSS 9.8
The kbase_dispatch function in arm/t7xx/r5p0/mali_kbase_core_linux.c in the GPU driver on Samsung devices with M(6.0) and N(7.0) software and Exynos AP chipsets allows attackers to have unspecified impact via unknown vectors, which trigger an out-of-bounds read, aka SVE-2016-6362.

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.
