LIN1022-22828 : Security Advisory - linux - CVE-2026-31682

Created: Apr 27, 2026    Updated: Apr 30, 2026
Found In Version: 10.22.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 22
Component/s: Kernel

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.
