Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

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.
