Details

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

net: esp: fix bad handling of pages from page_pool

When the skb is reorganized during espoutput (!esp->inline), the pages coming from the original skb fragments are supposed to be released back to the system through putpage. But if the skb fragment pages are originating from a pagepool, calling putpage on them will trigger a page_pool leak which will eventually result in a crash.

This leak can be easily observed when using CONFIGDEBUGVM and doing ipsec + gre (non offloaded) forwarding:

The suggested fix is to introduce a new wrapper (skbpageunref) that covers page refcounting for page_pool pages as well.
