Overview

CVE-2026-89514 is a known-severity vulnerability. It was published on September 11, 2026.

Technical description

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.
