CVE-2024-26641 ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: make sure to pull inner header in ip6tnlrcv syzbot found ip6tnlrcv could access unitiliazed data 1. Call pskbinetmaypull to fix this, and initialize ipv6h variable after this call as it can change skb-head. 1 BUG: KMSA...

CVE-2024-26641

CVE-2024-26641 concerns the Linux kernel. The vulnerability arises in ip6_tunnel, where __ip6_tnl_rcv() could access uninitialized data due to not pulling the inner header early enough. The fix, as noted in multiple advisories (e.g., Astra Linux security bulletins), is to call pskb_inet_may_pull(...

CVE-2024-26633

CVE-2024-26633 affects the Linux kernel’s ip6_tunnel code, specifically the NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim(). Syzbot reported that frag_off could be read before enough bytes were pulled into skb->head, causing reads of uninitialized or garbage data. The issue is exposed...
