CVE-2025-40232 Details
Description
In the Linux kernel, the following vulnerability has been resolved: rv: Fully convert enabled_monitors to use list_head as iterator The callbacks in enabled_monitors_seq_ops are inconsistent. Some treat the iterator as struct rv_monitor *, while others treat the iterator as struct list_head *. This causes a wrong type cast and crashes the system as reported by Nathan. Convert everything to use struct list_head * as iterator. This also makes enabled_monitors consistent with available_monitors.
A vulnerability in the Linux kernel's handling of the 'enabled_monitors' iterator has been addressed. The issue arose because the 'enabled_monitors_seq_ops' callbacks inconsistently treated the iterator as either a 'struct rv_monitor *' or a 'struct list_head *'. This inconsistency led to incorrect type casting, causing system crashes. The vulnerability affected the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability.
