CVE-2024-53134 is a vulnerability identified in the Linux kernel, specifically related to the 'imx93-blk-ctrl' component within the power management domain (pmdomain) subsystem. The issue arises from an incorrect loop termination condition in the code that manages domain removal. The original condition incorrectly uses 'bc->onecell_data.num_domains' as the loop boundary without a proper comparison operator, causing the loop to never finish. This leads to a kernel panic, which is a critical failure state causing the system to halt or reboot unexpectedly. Additionally, the vulnerability involves an unbalanced runtime power management enable/disable sequence, indicated by the message "imx93-blk-ctrl 4ac10000.system-controller: Unbalanced pm_runtime_enable!". This suggests improper handling of power management runtime states, which can further destabilize the system. The vulnerability affects specific Linux kernel versions identified by commit hashes, and the fix involves correcting the loop condition to 'i < bc->onecell_data.num_domains' and disabling runtime power management to prevent the unbalanced state. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet.

For European organizations, the impact of CVE-2024-53134 primarily concerns systems running Linux kernels that include the affected 'imx93-blk-ctrl' driver, which is typically associated with NXP i.MX93 series processors used in embedded and industrial devices. A kernel panic caused by this vulnerability can lead to denial of service (DoS), disrupting critical operations, especially in industrial control systems, IoT devices, and embedded platforms prevalent in sectors such as manufacturing, automotive, and telecommunications. The unbalanced runtime power management issue may also cause instability or unexpected reboots, affecting system availability and reliability. Confidentiality and integrity impacts are minimal since the vulnerability does not directly enable unauthorized access or code execution. However, the availability impact can be significant in environments relying on continuous operation. European organizations with embedded Linux devices or industrial systems using affected hardware could face operational disruptions, increased maintenance costs, and potential safety risks if devices fail unexpectedly.

To mitigate CVE-2024-53134, European organizations should: 1) Identify and inventory all devices running Linux kernels with the affected 'imx93-blk-ctrl' driver, focusing on embedded and industrial systems using NXP i.MX93 processors. 2) Apply the official Linux kernel patches that correct the loop condition and disable runtime power management for the affected component as soon as they become available from trusted sources or vendor updates. 3) For devices where patching the kernel is not immediately feasible, consider implementing monitoring and alerting for kernel panics or unexpected reboots to enable rapid response and minimize downtime. 4) Engage with hardware and software vendors to confirm the deployment of patched firmware or kernel versions. 5) Review power management configurations and runtime enable/disable sequences in custom kernel builds to ensure balanced and stable operation. 6) Test updates in controlled environments before wide deployment to avoid unintended side effects. 7) Maintain robust backup and recovery procedures to restore affected systems quickly in case of failure.
