Details

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

ext4: drop extent cache when splitting extent fails

When the split extent fails, we might leave some extents still being processed and return an error directly, which will result in stale extent entries remaining in the extent status tree. So drop all of the remaining potentially stale extents if the splitting fails.
