CVE-2024-27393: xen-netfront: Add missing skb_mark_for_recycle

Published May 8, 2024
·
Updated

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

xen-netfront: Add missing skbmarkforrecycle

Notice that skbmarkforrecycle() is introduced later than fixes tag in commit 6a5bcd84e886 ("pagepool: Allow drivers to hint on SKB recycling").

It is believed that fixes tag were missing a call to pagepoolreleasepage() between v5.9 to v5.14, after which is should have used skbmarkforrecycle(). Since v6.6 the call pagepoolreleasepage() were removed (in commit 535b9c61bdef ("net: pagepool: hide pagepoolreleasepage()") and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch 'net-pagepool-remove-pagepoolreleasepage'")).

This leak became visible in v6.8 via commit dba1b8a7ab68 ("mm/pagepool: catch pagepool memory leaks").
