Description Guilherme de Almeida Suckevicz 2019-11-26 13:40:41 UTC
A memory leak in the ca8210_probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering ca8210_get_platform_data() failures, aka CID-6402939ec86e.
