"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrivers/base/memory: set mem->altmap after successful device registration\n\nIf __add_memory_block() fails at xa_store() (under memory pressure for\nexample), device_unregister() is called, which eventually triggers\nmemory_block_release() with mem->altmap still set, causing a\nWARN_ON(mem->altmap). This was triggered by modifying virtio-mem driver.\n\nFix this by delaying the assignment of mem->altmap until after\n__add_memory_block() has succeeded."
