"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: octeon: add missing napi_disable in cvm_oct_rx_shutdown\n\ncvm_oct_rx_shutdown calls free_irq and netif_napi_del without\ndisabling the napi instance first. As the free_irq only waits\nfor completion of hard interrupt handlers, the napi poll\nfunction could still be active. If cvm_oct_remove proceeds to\nfree the plat structure (which holds the NAPI instances), the\nactive poll function will access freed memory, resulting in a\nuse-after-free crash."
