Lifecycle Timeline
3DescriptionCVE.org
A security flaw has been discovered in radareorg radare2 up to 6.1.6. This impacts the function r_str_word_get0set of the file libr/util/str.c. The manipulation results in integer overflow. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The patch is identified as 11ac224c0eb8d57830fccc99e1c1cd8e5d958813. It is best practice to apply a patch to resolve this issue.
AnalysisAI
Integer overflow in radare2's r_str_word_get0set function (libr/util/str.c) allows a local low-privileged attacker to crash the application on versions up to 6.1.6. The CWE-190 integer wraparound can produce a buffer overflow condition, degrading availability of the radare2 analysis session. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have local system access with at minimum a low-privilege user account (PR:L per CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N) scores 1.9, signaling genuinely low risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker with a standard unprivileged account on a system where radare2 is installed crafts a malformed input designed to trigger integer wraparound in `r_str_word_get0set`, causing an undersized buffer allocation and subsequent memory corruption that crashes the radare2 process. A public proof-of-concept demonstrating this crash is available via the GitHub issue at https://github.com/radareorg/radare2/issues/26047. … |
| Remediation | Apply upstream fix commit 11ac224c0eb8d57830fccc99e1c1cd8e5d958813 from the radare2 GitHub repository (https://github.com/radareorg/radare2/commit/11ac224c0eb8d57830fccc99e1c1cd8e5d958813). … Detailed patch versions, workarounds, and compensating controls in full report. |
