Description

In the Linux kernel, the following vulnerability has been resolved: ubifs: Set page uptodate in the correct place Page cache reads are lockless, so setting the freshly allocated page uptodate before we&#39;ve overwritten it with the data it&#39;s supposed to have in it will allow a simultaneous reader to see old data. Move the call to SetPageUptodate into ubifs_write_end(), which is after we copied the new data into the page.
