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. A flaw was found in the Linux kernel's bridge module. A remote attacker could exploit this by sending a malformed Neighbor Discovery (ND) option. This could cause the `br_nd_send()` function to improperly process option lengths, potentially leading to information disclosure or a denial of service (DoS).
