There can be a pending tasklet in\nthe queue which might run after the cvm_oct_remove() frees net_device\nstructures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it\niterates cvm_oct_device[] which is an array of netdevice pointers.\nAdd tasklet_kill() after free_irq() to ensure the tasklet is no longer\nscheduled or running before teardown proceeds.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
