Vulnerability Title
ip6_tunnel: fix NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim()
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: fix NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim()
syzbot pointed out [1] that NEXTHDR_FRAGMENT handling is broken.
Reading frag_off can only be done if we pulled enough bytes
to skb->head. Currently we might access garbage.
