Report: Complete Guide to CVE-2026-31682 - bridge: br_nd_send: linearize skb before parsing ND options

CVE ID :CVE-2026-31682 Published : April 25, 2026, 9:16 a.m. | 1 hour, 11 minutes ago Description :In the Linux kernel, the following vulnerability has been resolved: bridge: br_nd_send: linearize skb before parsing ND options br_nd_send() parses neighbour discovery options from ns->opt[] and assumes that these options are in the linear part of request. Its callers only guarantee that the ICMPv6 header and target address are available, so the option area can still be non-linear. Parsing ns->opt[] in that case can access data past the linear buffer. Linearize request before option parsing and derive ns from the linear network header.
