CVE-2026-98760 in Linux
Résumé
par MITRE • 18/10/2026
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.
If you want to get the best quality for vulnerability data then you always have to consider VulDB.
