CVE-2026-89514

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

scsi: fnic: Use GFP_ATOMIC for VLAN alloc under spinlock

fnic_fcoe_process_vlan_resp() allocates a VLAN descriptor with kzalloc_obj() (default GFP_KERNEL) while holding vlans_lock via spin_lock_irqsave(). GFP_KERNEL may sleep, which is not allowed in this atomic context and can trigger a sleeping-from-invalid-context warning or deadlock.

Pass GFP_ATOMIC so the allocation is safe under the IRQ-safe spinlock.
