Mitigating Controls (NIST 800-53 r5) AI

prevent

Input validation in set_cpu_affinity() would reject or sanitize references before the NULL dereference of npu_proto_drv.ast.thread_ref occurs.

prevent

Memory protection enforces safe pointer handling and can trap or prevent the NULL dereference that leads to DoS in the Exynos NPU driver.

prevent

Prompt remediation of the CWE-476 flaw in the Exynos 1380/1480/2400/1580/2500 NPU firmware eliminates the vulnerable code path.

PR.PS-06 mostly match
prevents

Secure SDLC practices (static analysis, code review, safe coding standards) directly prevent NULL dereference bugs during development.

detects

Security testing can detect NULL dereference defects before release.

prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

prevents

Application security requirements can specify input validation and pointer-safety rules.

prevents

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

prevents

Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
