CVE-2023-53850

Estado: AplazadaSin puntuar—

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

iavf: use internal state to free traffic IRQs

If the system tries to close the netdev while iavf_reset_task() is running, __LINK_STATE_START will be cleared and netif_running() will return false in iavf_reinit_interrupt_scheme(). This will result in iavf_free_traffic_irqs() not being called and a leak as follows:

is shown when pci_disable_msix() is later called. Fix by using the internal adapter state. The traffic IRQs will always exist if state == __IAVF_RUNNING.
