kmalloc_obj(), which\nis sizeof(struct edge_ti_manuf_descriptor) = 10 bytes.\n\nThe Size field comes from the device and is only validated (in\ncheck_i2c_image()) to make sure the descriptor fits within\nTI_MAX_I2C_SIZE (16384 bytes), not against the destination buffer size.\nA malicious USB device can therefore set Size to any value up to 16377,\ncausing a heap overflow of up to 16367 bytes when plugged into a host\nrunning this driver.\n\nvalid_csum() is called after read_rom() and also iterates\nbuffer[0..Size-1], compounding the out-of-bounds access.\n\nFix by rejecting descriptors with unexpected length before calling\nread_rom().\n\n[ johan: amend commit message; also check for short descriptors ]"}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus":
