Mitigating Controls (NIST 800-53 r5) AI

prevent

Memory Protection directly implements safeguards against use-after-free conditions in kernel drivers such as the Xclipse GPU driver.

prevent

Flaw Remediation requires timely patching of the identified use-after-free vulnerability in the Exynos GPU driver.

prevent

Process Isolation confines the GPU driver to its own execution domain, limiting the blast radius of a successful use-after-free exploit.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly incorporate memory-safety tooling and reviews that prevent most use-after-free defects.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover use-after-free issues via scanning or analysis but do not prevent their introduction.

PR.PS-02 partial match
prevents

Routine patching removes known use-after-free instances after they have been introduced in released software.

detects

Security testing in development can detect use-after-free bugs before release.

prevents

Secure SDLC mandates memory-safety practices that reduce use-after-free defects.

prevents

Application security requirements can specify memory-management rules that mitigate use-after-free.

prevents

Secure architecture principles include memory-safety design choices that limit use-after-free exposure.

prevents

Secure coding standards directly prescribe avoidance of use-after-free patterns.

prevents

Change-management processes help ensure memory-safety fixes are deployed consistently.
