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