CVE-2026-64554
CVE-2026-64554 affects the Linux kernel's Netfilter bridge path. The vulnerability occurs in br_ip6_fragment(), which obtains prevhdr (a pointer into the skb head) from ip6_find_1stfragopt() and then calls skb_checksum_help(). For cloned skbs, skb_checksum_help() reallocates the head via pskb_exp...
