Details

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

ppp_async: limit MRU to 64K

syzbot triggered a warning [1] in _allocpages():

WARNONONCEGFP(order > MAXPAGE_ORDER, gfp)

Willem fixed a similar issue in commit c0a2a1b0d631 ("ppp: limit MRU to 64K")

Adopt the same sanity check for pppasyncioctl(PPPIOCSMRU)
