CVE-2025-1864 is a critical-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Radare Radare2. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 40.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly requires identification, reporting, and correction of flaws like this buffer overflow via timely patching to radare2 version 5.9.9.
Implements memory protections such as address space layout randomization and non-executable memory to block exploitation of buffer overflows in radare2.
Mandates validation of inputs to radare2 to enforce proper bounds checking and prevent overflow operations within memory buffers.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in network-reachable radare2 component directly enables remote unauthenticated code execution matching T1190.
NVD Description
Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in radareorg radare2 allows Overflow Buffers.This issue affects radare2: before <5.9.9.
Deeper analysisAI
CVE-2025-1864 is an Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in radareorg's radare2 reverse engineering framework, enabling buffer overflows. This issue affects radare2 versions prior to 5.9.9 and is classified under CWE-119 and CWE-120. The vulnerability carries 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), indicating critical severity due to its potential for severe impacts across confidentiality, integrity, and availability.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows attackers to achieve high-impact effects, including unauthorized access to sensitive data, modification of system integrity, and disruption of availability, potentially leading to full system compromise on affected radare2 installations.
Mitigation is addressed via a patch in the radareorg/radare2 GitHub pull request at https://github.com/radareorg/radare2/pull/23981. Security practitioners should upgrade to radare2 version 5.9.9 or later to remediate the issue.
