In the Linux kernel, the following vulnerability has been resolved:
net: libwx: handle pagepooldevallocpages error
pagepooldevallocpages could return NULL. There was a WARN_ON(!page) but it would still proceed to use the NULL pointer and then crash.
This is similar to commit 001ba0902046 ("net: fec: handle pagepooldevallocpages error").
