Details

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

sched: actct: take care of padding in struct zonesht_key

Blamed commit increased lookup key size from 2 bytes to 16 bytes, because zoneshtkey got a struct net pointer.

Make sure rhashtable_lookup() is not using the padding bytes which are not initialized.
