Summary
net: airoha: fix foe_check_time allocation size
Details

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

net: airoha: fix foechecktime allocation size

foechecktime is declared as u16 pointer but was allocated with only ppenumentries bytes instead of ppenumentries * sizeof(u16).

When airohappefoeverifyentry() is called with hash >= ppenumentries/2, it writes beyond the allocated buffer, causing heap buffer overflow and potential kernel crash.
