Summary
In the Linux kernel, the following vulnerability has been resolved:
netfs: Call `invalidate_cache` only if implemented
Many filesystems such as NFS and Ceph do not implement the
`invalidate_cache` method. On those filesystems, if writing to the
cache (`NETFS_WRITE_TO_CACHE`) fails for some reason, the kernel
crashes like this:
BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor instruction fetch in kernel mode
