CVE-2026-89514

In the Linux kernel , the scsi: fnic driver's fnic_fcoe_process_vlan_resp() function allocates a VLAN descriptor using kzalloc_obj() with the default GFP_KERNEL flag while holding vlans_lock via spin_lock_irqsave(). Since GFP_KERNEL may sleep, this is invalid in the atomic context and can trigger...
