CVE-2022-50468: Linux kernel USB‑PD driver may fail to unload safely
CVE-2022-50468 · published 1 year ago
Summary
The USB Power Delivery driver in several Linux kernel builds could be removed without properly checking for errors, leading to warning messages and possible instability. This happens because the driver does not verify that it was registered correctly before proceeding. Updating the kernel to the latest version resolves the issue by adding the missing error check.

Original advisory text
platform/chrome: cros_usbpd_notify: Fix error handling in cros_usbpd_notify_init()
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.
