 https://github.com/torvalds/linux/commit/e13de8fe0d6a51341671bbe384826d527afe8d44
Description:
 ** DISPUTED ** A memory leak in the unittest_data_add() function in
 drivers/of/unittest.c in the Linux kernel before 5.3.10 allows attackers to
 cause a denial of service (memory consumption) by triggering
 of_fdt_unflatten_tree() failures, aka CID-e13de8fe0d6a. NOTE: third parties
 dispute the relevance of this because unittest.c can only be reached during
 boot.
Ubuntu-Description:
Notes:
 sbeattie> CONFIG_OF_UNITTEST is disabled in xenial-eoan
 sbeattie> in trusty and before, the option is CONFIG_OF_SELFTEST
