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.

A flaw was found in the Linux kernel's network file system (netfs) component. This vulnerability, known as 'tearing', occurs when the system attempts to update file size information (`remote_i_size` and `zero_point`) without proper synchronization. This can lead
