In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]kasan: remove kasan_find_vm_area() to prevent possible deadlock[EOL][EOL]find_vm_area() couldn't be called in atomic_context.  If find_vm_area() is[EOL]called to reports vm area information, kasan can trigger deadlock like:[EOL][EOL]CPU0                                CPU1[EOL]vmalloc();[EOL] alloc_vmap_area();[EOL]  spin_lock(&vn->busy.lock)[EOL]                                    spin_lock_bh(&some_lock);[EOL]   <interrupt occurs>[EOL]   <in softirq>[EOL]   spin_lock(&some_lock);[EOL]                                    <access invalid address>[EOL]                                    kasan_report();[EOL]                                     print_report();[EOL]                                      print_address_description();[EOL]                                       kasan_find_vm_area();[EOL]                                        find_vm_area();[EOL]                                         spin_lock(&vn->busy.lock) // deadlock![EOL][EOL]To prevent possible deadlock while kasan reports, remove kasan_find_vm_area().
