BELL-CVE-2026-89454

Affected: Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

fkie_cve-2026-89454

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

PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()

plda_init_interrupts() initializes IRQ domains and creates IRQ mapping but does not unwind them when later step fails.

If platform_get_irq() or either irq_create_mapping() fails in plda_init_interrupts(), the domains are never deinitialized. If irq_create_mapping() fails, port->intx_irq stays initialized.

Hence, remove the IRQ domains in the error path by calling plda_pcie_irq_domain_deinit().

Since plda_pcie_irq_domain_deinit() now disposes of the intx_irq and msi_irq mappings itself before removing their domains, the msi_irq mapping failure path can go directly to err_irq_domain_deinit instead of disposing of port->intx_irq separately first.
