CVE 설명
In the Linux kernel, the following vulnerability has been resolved:
llc: reserve device headroom for allocated frames
llc_alloc_frame() reserves link-layer headroom using the device type.
This is insufficient for stacked Ethernet devices such as VLAN devices,
where vlan_dev_hard_header() pushes a VLAN header before the lower
device's Ethernet header. An LLC response on such a device can
therefore underflow skb headroom in eth_header().
Use LL_RESERVED_SPACE() to account for the device's actual required
headroom while preserving the existing LLC device-type check.
