Описание
In the Linux kernel, the following vulnerability has been resolved:
i2c: core: fix adapter deregistration race
Adapters can be looked up by their id using i2c_get_adapter() which takes a reference to the embedded struct device.
Remove the adapter from the IDR before tearing it down during deregistration (and on registration failure) to make sure its resources are not accessed after having been freed (e.g. the device name).

In the Linux kernel, the following vulnerability has been resolved: i2c: core: fix adapter deregistration race Adapters can be looked up by their id using i2c_get_adapter() which takes a reference to the embedded struct device. Remove the adapter from the IDR before tearing it down during deregistration (and on registration failure) to make sure its resources are not accessed after having been freed (e.g. the device name).
A flaw was found in the Linux kernel, specifically within its I2C (Inter-Integrated Circuit) core component. This vulnerability involves a race condition that occurs when an I2C adapter is being removed from the system. During this process, it is possible for the system to attempt to access the adapter's memory after it has already been released. A local attacker could potentially exploit this issue, leading to system instability, unauthorized information access, or the execution of malicious code.
