Description

In the Linux kernel, the following vulnerability has been resolved: ARM: footbridge: fix PCI interrupt mapping Since commit 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in pci_device_probe()"), the PCI code will call the IRQ mapping function whenever a PCI driver is probed. If these are marked as __init, this causes an oops if a PCI driver is loaded or bound after the kernel has initialised.

Affected configurations

• linux linux kernel (>= 4.13.0 < 4.14.232) • linux linux kernel (>= 4.15.0 < 4.19.189) • linux linux kernel (>= 4.20.0 < 5.4.114) • linux linux kernel (>= 5.5.0 < 5.10.32) • linux linux kernel (>= 5.11.0 < 5.11.16)
