CVE-2024-46832

Summary

CVE-2024-46832 is a vulnerability affecting the Linux kernel on MIPS architecture. It was discovered that calling the function get_c0_compare_int was not allowed when a timer interrupt was installed on a secondary CPU. This issue resulted in a warning message about a sleeping function being called from an invalid context. The vulnerability was resolved by avoiding the call to get_c0_compare_int in such cases, as the struct clock_event_device *cd, to which the IRQ number was to be saved, is not used by the clockevent core for non-CPU local devices.
