CVE-2024-58015 is a vulnerability identified in the Linux kernel specifically affecting the ath12k wireless driver component. The issue arises from an out-of-bounds memory access caused by improper handling of buffer sizes in the function print_array_to_buf_index(). This function is responsible for placing self-generated statistics into a buffer. The vulnerability occurs because the array length parameter passed to this function is larger than the actual buffer size, leading to a potential out-of-bounds write or read. This memory error was discovered via static analysis using Coverity Scan (CID 1600742 and CID 1600758). The root cause is a faulty upper bound on the array length parameter, which can be mitigated by reducing the buffer size by one. While no known exploits are currently reported in the wild, the flaw could allow attackers to cause memory corruption, potentially leading to system instability, crashes, or privilege escalation if exploited. The affected versions are identified by specific Linux kernel commit hashes, indicating that this vulnerability is present in certain recent kernel builds. Since the vulnerability is in a wireless driver, exploitation would likely require local access or proximity to the wireless interface, but could also be triggered remotely if the wireless interface is exposed. No CVSS score has been assigned yet, and no patches or exploit code are publicly available at this time.

For European organizations, the impact of CVE-2024-58015 could be significant in environments relying heavily on Linux-based systems with wireless connectivity, such as enterprise networks, telecommunications infrastructure, and critical industrial control systems. The vulnerability could lead to denial of service through kernel crashes or potentially allow attackers to escalate privileges on affected systems, compromising confidentiality and integrity of data. Organizations with wireless access points or devices running vulnerable Linux kernels may face increased risk of targeted attacks, especially in sectors like finance, healthcare, and government where data sensitivity is high. Additionally, the potential for memory corruption could be leveraged as a foothold for further lateral movement within networks. Given the widespread use of Linux in European data centers and embedded systems, unpatched systems could be vulnerable to exploitation once exploit code becomes available. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, especially as attackers often reverse-engineer patches to develop exploits.

1. Immediate review and identification of Linux systems running affected kernel versions, particularly those using the ath12k wireless driver. 2. Apply kernel updates or patches as soon as they become available from trusted Linux distributions or kernel maintainers. 3. For environments where patching is delayed, consider disabling the ath12k wireless driver if not essential, or restricting wireless interface access to trusted users and networks. 4. Implement network segmentation to isolate critical systems and limit exposure of wireless interfaces. 5. Monitor system logs and kernel messages for signs of memory corruption or unusual wireless driver behavior. 6. Employ intrusion detection systems capable of detecting anomalous kernel or wireless driver activity. 7. Conduct regular security audits and vulnerability scans focusing on kernel and driver versions. 8. Educate system administrators about the risks associated with kernel vulnerabilities and the importance of timely patching.
