Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 5.10.162/5.15.85/6.0.15/6.1.1. This issue affects the function cros_usbpd_notify_init. The manipulation with an unknown input leads to a return value vulnerability. Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: cros_usbpd_notify: Fix error handling in cros_usbpd_notify_init() The following WARNING message was given when rmmod cros_usbpd_notify: Unexpected driver unregister! WARNING: CPU: 0 PID: 253 at drivers/base/driver.c:270 driver_unregister+0x8a/0xb0 Modules linked in: cros_usbpd_notify(-) CPU: 0 PID: 253 Comm: rmmod Not tainted 6.1.0-rc3 #24 ... Call Trace: <TASK> cros_usbpd_notify_exit+0x11/0x1e [cros_usbpd_notify] __x64_sys_delete_module+0x3c7/0x570 ? __ia32_sys_delete_module+0x570/0x570 ? lock_is_held_type+0xe3/0x140 ? syscall_enter_from_user_mode+0x17/0x50 ? rcu_read_lock_sched_held+0xa0/0xd0 ? syscall_enter_from_user_mode+0x1c/0x50 do_syscall_64+0x37/0x90 entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x7f333fe9b1b7 The reason is that the cros_usbpd_notify_init() does not check the return value of platform_driver_register(), and the cros_usbpd_notify can install successfully even if platform_driver_register() failed. Fix by checking the return value of platform_driver_register() and unregister cros_usbpd_notify_plat_driver when it failed.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-50468 since 10/01/2025. The exploitation is known to be difficult. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/17/2026).

Upgrading to version 5.10.163, 5.15.86, 6.0.16 or 6.1.2 eliminates this vulnerability. Applying the patch 5c0cacdd354987f8f5348d16908716f154047890/cab345f9d51943898e406275f9607c145adb1877/7b6ee54995739202b4a0cc01b7e9269f761c573d/751f12696d797e785d2611099fe9f0569d47556e/5a2d96623670155d94aca72c320c0ac27bdc6bd2 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the databases at EUVD (EUVD-2025-32826) and CERT Bund (WID-SEC-2025-2187). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
