"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nllc: reserve device headroom for allocated frames\n\nllc_alloc_frame() reserves link-layer headroom using the device type.\nThis is insufficient for stacked Ethernet devices such as VLAN devices,\nwhere vlan_dev_hard_header() pushes a VLAN header before the lower\ndevice's Ethernet header. An LLC response on such a device can\ntherefore underflow skb headroom in eth_header().\n\nUse LL_RESERVED_SPACE() to account for the device's actual required\nheadroom while preserving the existing LLC device-type check."
