  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: typec: tcpm: Validate SVID index in svdm_consume_modes()  In svdm_consume_modes(), the SVID value is read from pmdata-\u003esvids using pmdata-\u003esvid_index as an array index without bounds validation:      paltmode-\u003esvid = pmdata-\u003esvids[pmdata-\u003esvid_index];  If pmdata-\u003esvid_index is driven beyond SVID_DISCOVERY_MAX (16), it results in an out-of-bounds read of the pmdata-\u003esvids array. Because pd_mode_data is embedded inside struct tcpm_port, indexing past svids reads into adjacent fields. In particular: - At index 16, it reads the altmodes count. - At index 18 and beyond, it reads into altmode_desc[], which contains   partner-supplied SVDM Discovery Modes VDOs.  By injecting a chosen SVID into altmode_desc[0].vdo and driving svid_index to 20, the partner can force paltmode-\u003esvid to be loaded with an arbitrary, partner- chosen SVID, which is then registered via typec_partner_register_altmode().  Fix this by validating that pmdata-\u003esvid_index is non-negative and strictly less than pmdata-\u003ensvids before accessing the pmdata-\u003esvids array inside svdm_consume_modes().",
