"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: touchwin - reset the packet index on every complete packet\n\ntw_interrupt() accumulates each non-zero serial byte into a fixed\nthree-byte buffer with a running index that is only reset once a full\npacket has been received *and* the device's two Y bytes agree:\n\n\ttw->data[tw->idx++] = data;\n\tif (tw->idx == TW_LENGTH && tw->data[1] == tw->data[2]) {\n\t\t...\n\t\ttw->idx = 0;\n\t}\n\nThe reset is gated on tw->data[1] == tw->data[2], a value the device\ncontrols. A malicious, malfunctioning or counterfeit Touchwindow\nperipheral can stream non-zero bytes whose 2nd and 3rd bytes differ: the\nindex reaches TW_LENGTH without the equality holding, is never reset, and\nkeeps growing, so tw->data[tw->idx++] walks off the end of the three-byte\narray and the rest of the heap-allocated struct tw, one attacker-chosen\nbyte at a time -- an unbounded, device-driven heap out-of-bounds write.\n\nReset the index on every completed packet and report an event only when\nthe two Y bytes match, like the other serio touchscreen drivers do."
