Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=905f886eae4b065656a575e8a02544045cbaadcf



--------------------------------

commit 051ae669 upstream.

Validate that the IEEE80211_P2P_ATTR_OPER_CHANNEL attribute contains
enough space for a 'struct struct wilc_attr_oper_ch'. If the attribute is
too small then it triggers an out-of-bounds write later in the function.
