CVE-2026-14760 - Vulnerability Details

- radareorg radare2 regprofile disasm.c r_core_seek_arch_bits use after free

Description

A weakness has been identified in radareorg radare2 up to 6.1.6. Impacted is the function r_core_seek_arch_bits of the file libr/core/disasm.c of the component regprofile Handler. Executing a manipulation can lead to use after free. The attack requires local access. The exploit has been made available to the public and could be used for attacks. This patch is called 8b25c773785d85cb0103410a0905089d286921c2. It is advisable to implement a patch to correct this issue.

Analysis

Impact

This vulnerability is a use‑after‑free flaw in radareorg’s radare2, triggered in the r_core_seek_arch_bits function of the regprofile handler. An attacker with local file access can manipulate the function so that a freed pointer is dereferenced, resulting in memory corruption of the process.

Affected Systems

The flaw affects radare2 releases up to and including version 6.1.6. Any installation of those versions is vulnerable. The patch that resolves the issue is identified by commit 8b25c773785d85cb0103410a0905089d286921c2, and can be incorporated by rebuilding from the latest source tree.

Risk and Exploitability

The CVSS score of 4.8 indicates a moderate severity, while an EPSS score of less than 1% suggests that the probability of exploitation is currently low. The vulnerability is not listed in the CISA KEV catalog. An exploit is publicly available and requires only local privileges; any user with write access to a radare2 installation could trigger the flaw, leading to memory corruption of the process.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Apply the official patch identified by commit 8b25c773785d85cb0103410a0905089d286921c2 or upgrade radare2 to a release that incorporates this fix; the patch addresses the use‑after‑free flaw (CWE‑416) and associated memory corruption by ensuring freed memory is not dereferenced.
Rebuild radare2 from the patched source to ensure that buffer handling improvements (CWE‑119) and proper memory clearing (CWE‑825) are enforced throughout the codebase.
Restrict execution of radare2 to trusted users and disable the regprofile handler or the r_core_seek_arch_bits function if not required; limiting local access reduces the attack surface for the use‑after‑free vulnerability (CWE‑416).
