CVE-2022-50431 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: aoa: i2sbus: fix possible memory leak in i2sbus_add_dev() dev_set_name() in soundbus_add_one() allocates memory for name, it need be freed when of_device_register() fails, call soundbus_dev_put() to give up the reference that hold in device_initialize(), so that it can be freed in kobject_cleanup() when the refcount hit to 0. And other resources are also freed in i2sbus_release_dev(), so it can return 0 directly.
A memory leak vulnerability has been identified in the Linux kernel's ALSA AOA I2SBus component. The issue arises in the 'i2sbus_add_dev()' function, where 'dev_set_name()' allocates memory for the device name. If 'of_device_register()' fails, this memory is not properly freed, leading to a leak. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. Instructions for upgrading the Linux kernel can be found in the official Linux kernel documentation.
