When a partner device connects, the driver fails to properly initialize temporary memory structures allocated on the stack before registering the connection. An attacker connecting a USB Type-C device could exploit this flaw to trigger the execution of invalid memory pointers or leak internal stack data. This could result in a Denial of Service (DoS) via a system crash, arbitrary code execution, or information disclosure.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98760.json)\n\n**kernel: usb: typec: tipd: fix uninitialized typec_partner_desc in tps6598x_connect()** — rated Moderate by Red Hat.
