However, if ena_probe() fails\nafter ena_device_init() succeeds, the error path destroys the admin\nresources and eventually frees ena_dev without destroying the MMIO read\nrequest, leaving the coherent DMA buffer allocated.\n\nCall ena_com_mmio_reg_read_request_destroy() in the probe error path\nbefore releasing the remaining device resources.\n\nThis issue was found by manual code inspection.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
