platform/chrome: cros_usbpd_notify: Fix error handling in cros_usbpd_notify_init()
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
