CVE-2026-98760

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: tipd: fix uninitialized typec_partner_desc in tps6598x_connect()

tps6598x_connect() passes a stack-allocated typec_partner_desc to typec_register_partner() after initializing only usb_pd, accessory and identity.

typec_register_partner() copies attach and deattach from the descriptor into the partner. With those fields left unset, garbage function pointers may be stored and later invoked from typec_partner_link_device() when a USB device is linked to the port. Uninitialized pd_revision and usb_capability similarly leak stack data through partner sysfs.

Zero-initialize the descriptor so optional callbacks remain NULL and the remaining fields are zero.
