"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ena: fix MMIO read buffer leak on probe failure\n\nena_device_init() initializes the MMIO read mechanism with\nena_com_mmio_reg_read_request_init(), which allocates a coherent DMA\nbuffer for MMIO read responses.\n\nThe normal removal path releases this buffer through\nena_com_mmio_reg_read_request_destroy(). 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."
