"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: bridge: avoid recursive multicast port cleanup\n\nbr_multicast_sg_del_exclude_ports() removes automatically added STAR_EXCL\nport groups by calling br_multicast_del_pg(). For S,G entries, that\ndeletion calls back into br_multicast_sg_del_exclude_ports(), so a large\nnumber of STAR_EXCL ports consumes one kernel stack frame per port and can\nhit the stack guard page.\n\nKeep the complete port-group deletion path for cleanup, but suppress the\nS,G exclude-port cleanup while that helper is already walking the same\nentry. Normal deletion callers retain the existing behavior."
