ASA-2019-00644 – Linux kernel: A memory leak in ql_alloc_large_buffers()

A memory leak in the ql_alloc_large_buffers() function in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux kernel allows local users to cause a denial of service (memory consumption) by triggering pci_dma_mapping_error() failures.

ASA-2019-00643 – Linux kernel: Two memory leaks in sja1105_static_config_upload()

Two memory leaks in the sja1105_static_config_upload() function in drivers/net/dsa/sja1105/sja1105_spi.c in the Linux kernel allow attackers to cause a denial of service (memory consumption) by triggering static_config_buf_prepare_for_upload() or sja1105_inhibit_tx() failures.

ASA-2019-00639 – Linux kernel: Memory leak in sof_set_get_large_ctrl_data()

A memory leak in the sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c in the Linux kernel allows attackers to cause a denial of service (memory consumption) by triggering sof_get_ctrl_copy_params() failures.
