Vulnerability from github – Published: 2025-12-24 15:30 – Updated: 2026-08-04 12:34

Details

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

phy: tegra: xusb: Clear the driver reference in usb-phy dev

For the dual-role port, it will assign the phy dev to usb-phy dev and use the port dev driver as the dev driver of usb-phy.

When we try to destroy the port dev, it will destroy its dev driver as well. But we did not remove the reference from usb-phy dev. This might cause the use-after-free issue in KASAN.

Severity

7.8 (High)

No physical device insertion is needed since the padctl is an on-SoC platform device.\nAC:L - The dangling `dev.driver` and its subsequent dereference occur deterministically in the same teardown sequence \u2014 `devres_release_all()` frees the fake `device_driver` in `device_del(\u0026port-\u003edev)` and `phy_destroy()` reads it moments later \u2014 with no race the attacker cannot influence. The freed object is a small kmalloc allocation that a local attacker can reliably groom.\nPR:L - Exploitation of the freed `struct device_driver` \u2014 spraying the slab so the driver core reads attacker-controlled `pm`/`name` fields \u2014 is performed by an ordinary unprivileged local process, and the same teardown also executes on the boot-time probe-failure path with no privilege at all. Consistent with prior scoring of driver-remove-path use-after-frees in this subsystem class, PR:L is the higher defensible value.\nUI:N - No victim action is required; the use-after-free occurs automatically within the driver removal/probe-failure sequence. The attacker only needs to have its heap spray in place.\nS:U - Both the freed object and the code dereferencing it live in the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel memory-safety defect.\nC:H - The stale pointer is read by `dev_driver_string()` (`drv-\u003ename` passed to printk) and by `device_pm_check_callbacks()`, so reallocated heap contents can be dereferenced and leaked into kernel logs. Per use-after-free guidance, control over the freed object\u0027s contents yields an arbitrary-read primitive.\nI:H - `__rpm_get_callback()` loads a function pointer out of `dev-\u003edriver-\u003epm` on the freed object and invokes it, giving a direct control-flow hijack primitive once the slab object is reallocated with attacker-controlled data. Use-after-free of a structure containing function pointers is treated as High integrity impact.\nA:H - The KASAN-reported use-after-free dereferences freed memory during device removal, producing an oops or panic even without deliberate exploitation. Any kernel crash is scored High."
