"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: tcpm: Validate SVID index in svdm_consume_modes()\n\nIn svdm_consume_modes(), the SVID value is read from pmdata->svids using\npmdata->svid_index as an array index without bounds validation:\n\n paltmode->svid = pmdata->svids[pmdata->svid_index];\n\nIf pmdata->svid_index is driven beyond SVID_DISCOVERY_MAX (16), it results\nin an out-of-bounds read of the pmdata->svids array. Because pd_mode_data\nis embedded inside struct tcpm_port, indexing past svids reads into\nadjacent fields. In particular:\n- At index 16, it reads the altmodes count.\n- At index 18 and beyond, it reads into altmode_desc[], which contains\n partner-supplied SVDM Discovery Modes VDOs.\n\nBy injecting a chosen SVID into altmode_desc[0].vdo and driving svid_index\nto 20, the partner can force paltmode->svid to be loaded with an arbitrary,\npartner- chosen SVID, which is then registered via\ntypec_partner_register_altmode().\n\nFix this by validating that pmdata->svid_index is non-negative and strictly\nless than pmdata->nsvids before accessing the pmdata->svids array inside\nsvdm_consume_modes()."
