CVE-2026-43037

CVE-2026-43037 affects the Linux kernel; vulnerability arises from ip4ip6_err() using a cloned skb where the IPv6 receive path writes cb[] as inet6_skb_parm, which is then misinterpreted as IPv4 inet_skb_parm by __ip_options_echo(), causing a potential data leak/compromise. The fix includes clear...

CVE-2026-43038

CVE-2026-43038 affects the Linux kernel IPv6 ICMP error path. A forged IPv4 ICMP error with CIPSO options could cause ip6_err_gen_icmpv6_unreach() to misinterpret an inner IPv4 inet_skb_parm as an IPv6 parameter, allowing an offset misreference (dsthao) that could enable out-of-bounds or memory a...
