CVE-2026-31752 at MITRE

Description

In the Linux kernel, the following vulnerability has been resolved:

bridge: br_nd_send: validate ND option lengths

br_nd_send() walks ND options according to option-provided lengths.
A malformed option can make the parser advance beyond the computed
option span or use a too-short source LLADDR option payload.

Validate option lengths against the remaining NS option area before
advancing, and only read source LLADDR when the option is large enough
for an Ethernet address.
