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: iio: gyro: mpu3050: Move iio_device_register() to correct location iio_device_register() should be at the end of the probe function to prevent race conditions. Place iio_device_register() at the end of the probe function and place iio_device_unregister() accordingly.

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.

How this class of weakness works · CWE-362

Two operations that should be atomic can interleave, so an attacker who wins a narrow timing window reaches an inconsistent, exploitable state. These bugs are subtle and easy to miss in review. Fixing them properly means correct locking or atomic operations around the shared resource.

Recommended fix High confidence

Upgrade to kernel version 5.10.253+, 5.15.203+, 6.1.168+, or 6.6.134+ as appropriate for your distribution

  1. 1. Obtain the kernel source code for your currently running kernel version
  2. 2. Apply the vendor patch commit 051ca43b0e0e4b66bfd349cd53ccf231ad1d69b7 from git.kernel.org/stable/
  3. 3. The patch moves iio_device_register() to the end of the mpu3050_probe() function in drivers/iio/gyro/mpu3050.c
  4. 4. Recompile the kernel with the patched driver
  5. 5. Reboot into the updated kernel
  6. 6. Verify the mpu3050 driver loads correctly and the IIO device is registered
