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