CVE-2024-48241 is a vulnerability identified in the radare2 open-source reverse engineering framework, specifically affecting versions 5.8.0 through 5.9.4. The issue arises from improper handling within the __bf_div function, which is likely related to a buffer overflow or out-of-bounds write (CWE-787). This flaw permits a local attacker with low privileges to trigger a denial of service condition by causing the application to crash or become unresponsive. The vulnerability does not compromise confidentiality or integrity but impacts availability by disrupting normal operation. The attack vector is local, requiring the attacker to have access to the system where radare2 is installed. The attack complexity is low, and no user interaction is needed, making exploitation feasible in environments where local access is possible. No known exploits have been reported in the wild, and no official patches have been published yet. The CVSS v3.1 base score is 5.5, reflecting a medium severity rating. This vulnerability is significant for users of radare2, especially in security research, malware analysis, and software debugging contexts where radare2 is commonly deployed.

The primary impact of CVE-2024-48241 is denial of service, which can interrupt or halt reverse engineering or debugging workflows that rely on radare2. This disruption can delay incident response, malware analysis, or software debugging activities, potentially affecting organizational security operations and development cycles. Since the vulnerability requires local access, it limits the attack surface to insiders or attackers who have already compromised a system. There is no direct risk to data confidentiality or integrity, but availability loss can degrade operational efficiency and increase risk exposure if critical analysis tools become unusable. Organizations relying heavily on radare2 for security research or forensic investigations may experience workflow interruptions. The lack of known exploits reduces immediate risk, but the presence of a publicly disclosed vulnerability could motivate attackers to develop exploits, increasing future risk.

To mitigate CVE-2024-48241, organizations should restrict local access to systems running vulnerable radare2 versions, ensuring only trusted users have permission to execute the tool. Employing strict access controls and monitoring local user activity can reduce the risk of exploitation. Users should track radare2 project updates closely and apply patches promptly once available. As a temporary workaround, consider using alternative reverse engineering tools or earlier/later radare2 versions not affected by this vulnerability, if feasible. Implementing system-level protections such as sandboxing radare2 processes or running them with minimal privileges can limit the impact of a potential crash. Additionally, maintaining comprehensive system and application logs will aid in detecting exploitation attempts. Security teams should educate users about the risk of local exploitation and enforce policies to prevent unauthorized local access.
