Lifecycle Timeline
3DescriptionCVE.org
A security vulnerability has been detected in radareorg radare2 up to 6.1.6. Affected by this vulnerability is the function r_core_bin_load of the file libr/core/cfile.c. Such manipulation leads to use after free. The attack needs to be performed locally. The exploit has been disclosed publicly and may be used. The name of the patch is 635ab1eeb30340c26076722a90cb91fb2272130b. Applying a patch is advised to resolve this issue.
AnalysisAI
Use-after-free in radare2's r_core_bin_load function (libr/core/cfile.c) affects all versions up to and including 6.1.6, allowing a local low-privileged user to trigger memory corruption resulting in a denial of service. A public proof-of-concept exists (GitHub issue #26049), confirmed by the CVSS 4.0 E:P exploitability modifier, though the vulnerability is not listed in CISA KEV and no confirmed widespread active exploitation is known. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local user account with at least low-privilege access (confirmed by PR:L in the CVSS 4.0 vector) capable of executing radare2 and invoking the binary loading functionality via r_core_bin_load in libr/core/cfile.c. … 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 places this firmly in the medium tier with a score of 4.8. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with local system access places a specially crafted binary file on the target system and either directly invokes radare2 to load it, or social-engineers a security analyst into opening the file for reverse engineering. When r_core_bin_load processes the malicious binary, the use-after-free condition is triggered, causing radare2 to crash. … |
| Remediation | The upstream fix is available as commit 635ab1eeb30340c26076722a90cb91fb2272130b, accessible at https://github.com/oldzhu/radare2/commit/635ab1eeb30340c26076722a90cb91fb2272130b. … Detailed patch versions, workarounds, and compensating controls in full report. |
