Details

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

netfs: Fix netfspagemkwrite() to check folio->mapping is valid

Fix netfspagemkwrite() to check that folio->mapping is valid once it has taken the folio lock (as filemappagemkwrite() does). Without this, generic/247 occasionally oopses with something like the following:

BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page

RIP: 0010:trace_event_raw_event_netfs_folio+0x61/0xc0

This is due to the invalidateinodepages2_range() issued at the end of the DIO write interfering with the mmap'd writes.
