Type Casting Issue in Linux Kernel Leads to System Crash for Affected Users

CVE-2025-40232

What is CVE-2025-40232?

A critical type casting issue has been identified in the Linux kernel related to iterator handling in enabled_monitors. The inconsistency in callback functions, where some treat the iterator as 'struct rv_monitor *' and others as 'struct list_head *', can lead to wrong type casts. This inconsistency can cause system crashes, impacting system stability for affected users. The development team has addressed this by standardizing the iterator usage to 'struct list_head *', ensuring consistency with 'available_monitors' and preventing future crashes.
