"value": "The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code."

Esto ocurre porque la etiqueta de flujo autom\u00e1tico de un paquete UDP IPv6 se basa en un valor hashrnd de 32 bits como secreto y porque se usa jhash (en lugar de siphash). El valor hashrnd permanece igual a partir del tiempo de arranque, y puede ser inferido por un atacante. Esto afecta a net / core / flow_dissector.c y al c\u00f3digo relacionado."
