CVE-2024-40915

The CVE-2024-40915 issue affects the Linux kernel on riscv, where __kernel_map_pages() (a debugging page-table helper) used __set_memory() to flip the valid bit of page-table entries. __set_memory() takes init_mm’s semaphore and can sleep, but __kernel_map_pages() may be called in atomic context,...
