CVE-2026-98526
The Linux kernel contains a vulnerability in how the llc_alloc_frame() function reserves link-layer headroom. The current implementation uses the device type, which is insufficient for stacked Ethernet devices like VLAN devices . Because vlan_dev_hard_header() inserts a VLAN header before the low...
