Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires identification, reporting, and timely correction of flaws like the heap-based buffer overflow in radare2 versions before 5.9.9 via patching.

SI-16 Memory Protection partial match

prevent

Implements memory protections such as non-executable heap and address space randomization to mitigate exploitation of out-of-bounds writes and overflows.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Enables scanning and monitoring to identify deployments of vulnerable radare2 versions affected by CVE-2025-1744 for remediation.

NVD Description

Out-of-bounds Write vulnerability in radareorg radare2 allows heap-based buffer over-read or buffer overflow.This issue affects radare2: before <5.9.9.

Deeper analysisAI

CVE-2025-1744 is an out-of-bounds write vulnerability in radareorg radare2 that allows heap-based buffer over-read or buffer overflow. The issue affects radare2 versions before 5.9.9 and is classified under CWE-787.

With a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), the vulnerability can be exploited remotely by an unauthenticated attacker with low complexity and no user interaction. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary heap memory read or write operations.

The vulnerability is addressed via a patch in the GitHub pull request at https://github.com/radareorg/radare2/pull/23969. Affected users should update to radare2 version 5.9.9 or later to mitigate the issue.
