Summary

CVE-2026-4010 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability. Its CVSS base score is 4.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Vulnerability Data

A vulnerability was found in ThakeeNathees pocketlang up to cc73ca61b113d48ee130d837a7a8b145e41de5ce. The affected element is the function pkByteBufferAddString. The manipulation of the argument length with the input 4294967290 results in memory corruption. The attack requires a local approach. The exploit has…

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Local memory corruption (CWE-119) in pkByteBufferAddString directly enables local exploitation for privilege escalation via crafted length input causing buffer issues and potential code execution.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly blocks the oversized length argument (4294967290) from reaching pkByteBufferAddString before memory corruption occurs.

prevent

Enforces hardware-enforced memory protections (e.g., NX, ASLR, guard pages) that contain or abort exploitation of the CWE-119 buffer overflow.

prevent

Isolates the pocketlang process so that memory corruption in pkByteBufferAddString cannot affect other system components.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.
