One of the first features merged for the 5.10 kernel development cycle was support for the Arm v8.5 memory tagging extension [PDF]. By adding a "key" value to pointers, this mechanism enables the automated detection of a wide range of memory-safety issues. The result should be safer and more secure code — once support for the feature shows up in actual hardware.
