      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Fix stack-out-of-bounds write in devmap\n\nget_upper_ifindexes() iterates over all upper devices and writes their\nindices into an array without checking bounds.\n\nAlso the callers assume that the max number of upper devices is\nMAX_NEST_DEV and allocate excluded_devices[1+MAX_NEST_DEV] on the stack,\nbut that assumption is not correct and the number of upper devices could\nbe larger than MAX_NEST_DEV (e.g., many macvlans), causing a\nstack-out-of-bounds write.\n\nAdd a max parameter to get_upper_ifindexes() to avoid the issue.\nWhen there are too many upper devices, return -EOVERFLOW and abort the\nredirect.\n\nTo reproduce, create more than MAX_NEST_DEV(8) macvlans on a device with\nan XDP program attached using BPF_F_BROADCAST | BPF_F_EXCLUDE_INGRESS.\nThen send a packet to the device to trigger the XDP redirect path.",
