Vulnerability Data
In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User…

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces bounds checking on untrusted input to block the missing-bounds-check out-of-bounds write described in the CVE.
Requires hardware or OS memory-protection mechanisms that detect or block out-of-bounds writes before they can corrupt memory and escalate privilege.
Limits the set of privileges available to the process or user, reducing the impact of successful local privilege escalation even if the memory write succeeds.

Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.
Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.
Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

Security testing in development and acceptance can detect and prevent out-of-bounds write defects.
Secure development life cycle mandates practices that prevent out-of-bounds writes.
Application security requirements can specify bounds-checking and safe memory handling.
Secure architecture and engineering principles reduce the likelihood of buffer overflows.
Secure coding directly addresses out-of-bounds writes through language choice and coding standards.
Change management can enforce review gates that catch unsafe memory operations before deployment.
