  "message": "bootconfig: Reject unexpected data after null character\n\nIf a bootconfig buffer contains an intermediate null character in the\nmiddle of the configuration, xbc_parse_tree() stops at the null character\nbecause string delimiter searches (e.g. strpbrk()) stop at \u0027\\0\u0027, and\ncleanly breaks out of the loop without error. As a result, any\nconfiguration data following the intermediate null character is silently\nignored, allowing unparsed or potentially malicious data to be hidden\nafter an early termination.\n\nFix this in xbc_parse_tree() by checking that no non-null data remains\nbetween the parser termination point and the end of the input buffer.\nTrailing null characters (such as alignment padding in initrd) continue\nto be accepted as valid.\n\nAlso update apply_xbc() in tools/bootconfig/main.c to calculate the\nbuffer size based on the loaded file size rather than strlen(), so that\nfiles with intermediate null characters are not truncated before\nvalidation.\n\nLink: https://lore.kernel.org/all/178913598628.248794.1048773774471250986.stgit@devnote2/\n\nAssisted-by: LLM\nSigned-off-by: Masami Hiramatsu (Google) \u003cmhiramat@kernel.org\u003e\nReviewed-by: Sang-Heon Jeon \u003cekffu200098@gmail.com\u003e\n",
