Title
net: hsr: must allocate more bytes for RedBox support
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hsr: must allocate more bytes for RedBox support
Blamed commit forgot to change hsr_init_skb() to allocate
larger skb for RedBox case.
Indeed, send_hsr_supervision_frame() will add
two additional components (struct hsr_sup_tlv
and struct hsr_sup_payload)
syzbot reported the following crash:
