      "title": "HID: magicmouse: prevent unbounded recursion in magicmouse_raw_event()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: magicmouse: prevent unbounded recursion in magicmouse_raw_event()\n\nmagicmouse_raw_event() handles DOUBLE_REPORT_ID (0xf7) packets, which pack\ntwo touch reports into one, by splitting the packet and calling itself on\neach half. The only guard against runaway recursion is a \"size < 1\" check,\nwhich stops zero-sized calls but does not bound the recursion depth.\n\nA malicious HID device that matches this driver can send a report starting\nwith DOUBLE_REPORT_ID and filled with the sequence [0xf7, 0x00]. Each level\nconsumes two bytes and recurses on the remainder, so an incoming report of\nup to HID_MAX_BUFFER_SIZE (16 KiB) drives roughly 8000 nested calls. That\neasily exhausts the 16 KiB kernel stack, leading to a stack overflow: a\npanic with CONFIG_VMAP_STACK, or memory corruption without it.\n\nA double report only ever wraps two normal reports; it is never\nlegitimately nested. Refuse to re-enter the DOUBLE_REPORT_ID case from a\nrecursive call so the recursion depth is bounded to two, while all valid\npackets keep being parsed exactly as before.",
