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

netfs: Fix potential for tearing in ->remote_i_size and ->zero_point

Fix potential tearing in using ->remote_i_size and ->zero_point by copying

i_size_read() and i_size_write() and using the same seqcount as for i_size.

We need to make sure that netfslib and the filesystems that use it always

hold i_lock whilst updating any of the sizes to prevent i_size_seqcount

from getting corrupted. (NVD)
