In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix invalid access to memory
In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean
is_continuation is part of rxcb.
Currently, after freeing the skb, the rxcb->is_continuation accessed
again which is wrong since the memory is already freed.
This might lead use-after-free error.
Hence, fix by locally defining bool is_continuation from rxcb,
so that after freeing skb, is_continuation can be used.
Compile tested only.
