Title
netfs: Fix partial invalidation of streaming-write folio
Summary
In the Linux kernel, the following vulnerability has been resolved: netfs: Fix partial invalidation of streaming-write folio In netfs_invalidate_folio(), if the region of a partial invalidation overlaps the front (but not all) of a dirty write cached in a streaming write page (dirty, but not uptodate, with the dirty region tracked by a netfs_folio struct), the function modifies the dirty region - but incorrectly as it moves the region forward by setting the start to the start, not the end, of the invalidation region. Fix this by setting finfo->dirty_offset to the end of the invalidation region (iend).
Severity
