"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback\n\noctep_vf_request_irqs() requests MSI-X queue IRQs with dev_id set to\nioq_vector. If request_irq() fails part-way, the rollback loop calls\nfree_irq() with dev_id set to 'oct', which does not match the original\ndev_id and may leave the irqaction registered.\n\nThis can keep IRQ handlers alive while ioq_vector is later freed during\nunwind/teardown, leading to a use-after-free or crash when an interrupt\nfires.\n\nFix the error path to free IRQs with the same ioq_vector dev_id used\nduring request_irq()."

"value": "AV:L - The vulnerability is in a PCI device driver (Marvell Octeon EP VF) triggered via ndo_open when bringing up the network interface locally. It is not reachable remotely via network packets.\nAC:H - Exploitation requires request_irq() to fail partway through the loop (some IRQs allocated, then one fails), which depends on system resource conditions the attacker cannot reliably control.\nPR:L - Bringing up a VF network interface requires CAP_NET_ADMIN. In SR-IOV/container environments, VFs are commonly assigned to containers where users have CAP_NET_ADMIN via network namespaces, making this reachable without real root.\nUI:N - No user interaction is required; the attacker directly brings up the network interface.\nS:U - The vulnerability impacts the kernel within the same security authority; no security boundary (VM, sandbox) is crossed.\nC:H - The use-after-free in the IRQ handler allows reading freed ioq_vector memory, which could be reallocated with attacker-controlled content, enabling arbitrary kernel memory disclosure.\nI:H - The use-after-free allows the IRQ handler to operate on attacker-controlled data via heap spraying the freed ioq_vector, potentially enabling control flow hijacking and code execution.\nA:H - The use-after-free will crash the kernel when the interrupt handler dereferences freed/corrupted memory, causing an oops or panic."
