Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was identified in radareorg radare2 up to 6.1.6. This vulnerability affects the function cmd_anal_opcode of the file libr/core/cmd_anal.inc.c of the component hexpairs Parser. Such manipulation leads to integer overflow. The attack needs to be performed locally. The exploit is publicly available and might be used. The name of the patch is 84e773986e7e5bb30453a9384f498ec0ccc9d0a9. A patch should be applied to remediate this issue.
AnalysisAI
Integer overflow in radare2's hexpairs parser crashes the process for local low-privilege users on versions up to 6.1.6. The flaw exists in the cmd_anal_opcode function within libr/core/cmd_anal.inc.c and produces only a low availability impact with no confidentiality or integrity consequences. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local account with at minimum low-privilege access on the host running radare2 - remote exploitation is not possible per the CVSS 4.0 AV:L vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 1.9 accurately reflects a very low-severity finding. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local user with low-privilege access invokes radare2 and supplies a specially crafted hexpairs string to the `cmd_anal_opcode` command interface, triggering an integer overflow in the parser. The overflow causes the radare2 process to crash, producing a denial-of-service condition. … |
| Remediation | Apply the upstream fix commit 84e773986e7e5bb30453a9384f498ec0ccc9d0a9 available at https://github.com/radareorg/radare2/commit/84e773986e7e5bb30453a9384f498ec0ccc9d0a9. … Detailed patch versions, workarounds, and compensating controls in full report. |
