CVE-2026-23013

Description

In the Linux kernel, the following vulnerability has been resolved:net: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollbackoctep_vf_request_irqs() requests MSI-X queue IRQs with dev_id set toioq_vector. If request_irq() fails part-way, the rollback loop callsfree_irq() with dev_id set to oct, which does not match the originaldev_id and may leave the irqaction registered.This can keep IRQ handlers alive while ioq_vector is later freed duringunwind/teardown, leading to a use-after-free or crash when an interruptfires.Fix the error path to free IRQs with the same ioq_vector dev_id usedduring request_irq().
