CVE-2024-56678: powerpc/mm/fault: Fix kfence page fault reporting

Published Dec 28, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved:

powerpc/mm/fault: Fix kfence page fault reporting

copyfromkernelnofault() can be called when doing read of /proc/kcore. /proc/kcore can have some unmapped kfence objects which when read via copyfromkernelnofault() can cause page faults. Since nofault() functions define their own fixup table for handling fault, use that instead of asking kfence to handle such faults.

Hence we search the exception tables for the nip which generated the fault. If there is an entry then we let the fixup table handler handle the page fault by returning an error from within dopagefault().

This can be easily triggered if someone tries to do dd from /proc/kcore. eg. dd if=/proc/kcore of=/dev/null bs=1M

Some example false negatives:
