Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Upgrade available Upgrade to 5.10.163 / 5.15.86 / 6.0.16 or later
Fixed in 5.10.1635.15.866.0.16
Vendor patch git.kernel.org →
Recommended fix High confidence

5.10.163, 5.15.86, 6.0.16, or 6.1.2 (or later versions in each respective branch)

  1. Identify the current running kernel version using `uname -r`
  2. Determine which branch of the affected versions your kernel falls into based on the version ranges: >= 5.7 & < 5.10.163, >= 5.11 & < 5.15.86, >= 5.16 & < 6.0.16, or >= 6.1 & < 6.1.2
  3. Upgrade the Linux kernel to one of the fixed releases: 5.10.163 or later in the 5.10.x branch, 5.15.86 or later in the 5.15.x branch, 6.0.16 or later in the 6.0.x branch, or 6.1.2 or later in the 6.1.x branch
  4. Reboot the system into the new kernel
  5. Verify the fix is applied by checking that `cros_usbpd_notify` module can be loaded and unloaded without the 'Unexpected driver unregister' warning
Caveat Kernel upgrades may require matching kernel modules and could have compatibility implications with user-space tools; ensure all necessary drivers are available in the target version
