CVE-2024-57912 is a vulnerability identified in the Linux kernel specifically affecting the Industrial I/O (IIO) subsystem's pressure sensor driver for the zpa2326 device. The issue arises from improper initialization of a local struct named 'sample' used to transfer sensor data from kernel space to user space via a triggered buffer. This struct contains fields for pressure (u32), temperature (u16), and a timestamp (u64), with an uninitialized memory gap between the temperature and timestamp fields. Because this gap is never zeroed out before the struct is copied to user space, it can leak residual kernel memory contents. This constitutes an information leak vulnerability, potentially exposing sensitive kernel memory data to unprivileged userspace processes that have access to the triggered buffer interface of the zpa2326 pressure sensor driver. The fix involves explicitly zero-initializing the entire struct before populating it with sensor data, thereby preventing uninitialized memory from being exposed. Although no known exploits are currently reported in the wild, the vulnerability represents a subtle but real risk of unintended kernel memory disclosure through a device driver interface. The affected versions are specific Linux kernel commits identified by their hashes, indicating this is a recent and targeted fix in the kernel source code. No CVSS score has been assigned yet, and no patch links are provided in the data, but the vulnerability has been officially published and reserved in early 2025.

For European organizations, the impact of CVE-2024-57912 is primarily related to confidentiality breaches. The vulnerability allows an attacker with access to the affected sensor interface to read uninitialized kernel memory, which could contain sensitive information such as cryptographic keys, passwords, or other kernel data. While this does not directly allow privilege escalation or remote code execution, the leakage of kernel memory can aid attackers in further attacks or reconnaissance. Organizations relying on Linux systems with the affected kernel versions and hardware using the zpa2326 pressure sensor (commonly found in embedded or IoT devices, industrial control systems, or specialized hardware) could be at risk. This is particularly relevant for sectors like manufacturing, critical infrastructure, or research institutions using such sensors. The vulnerability requires local access to the device interface, so remote exploitation is unlikely without prior compromise. However, insider threats or compromised user accounts could exploit this to gather sensitive data. The lack of known exploits reduces immediate risk, but the subtlety of the leak means it could be used stealthily. Overall, the impact is moderate but should not be ignored in environments where sensor data interfaces are exposed or accessible.

To mitigate CVE-2024-57912, European organizations should: 1) Ensure that Linux kernel versions are updated promptly to include the fix that zero-initializes the 'sample' struct in the zpa2326 driver. This may require tracking kernel updates or applying patches from trusted sources. 2) Audit systems for the presence of the zpa2326 pressure sensor hardware and assess whether the sensor interface is exposed to unprivileged users or processes. 3) Restrict access permissions to the triggered buffer device files associated with the sensor to trusted users only, minimizing the attack surface. 4) Implement monitoring and logging of access to sensor interfaces to detect unusual or unauthorized usage patterns. 5) For embedded or IoT devices using this sensor, coordinate with hardware vendors to obtain firmware or kernel updates that address this vulnerability. 6) Conduct security reviews of other IIO subsystem drivers to identify similar uninitialized memory risks. 7) Educate system administrators about the risk of information leaks through device drivers and the importance of applying kernel security patches promptly.
