CVE-2026-31752 bridge: br_nd_send: validate ND option lengths

In the Linux kernel, the following vulnerability has been resolved: bridge: brndsend: validate ND option lengths brndsend 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...

CVE-2026-31682 bridge: br_nd_send: linearize skb before parsing ND options

In the Linux kernel, the following vulnerability has been resolved: bridge: brndsend: linearize skb before parsing ND options brndsend 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...

CVE-2026-31682

CVE-2026-31682 affects the Linux kernel bridge implementation, where br_nd_send may parse non-linear ND options from ns->opt[]. The root cause is failure to linearize the skb before ND option parsing, risking reads past the buffer and potential memory exposure or crash. The fix is to linearize...
