Description
In the Linux kernel, the following vulnerability has been resolved: nvmem: core: fix use-after-free bugs in error paths Fix several instances of error paths in which we call __nvmem_device_put() - which may end up freeing the underlying memory and other resources - and then keep on using the nvmem structure. Always put the reference to the nvmem device as the last step before returning the error code.

Executive Summary

This vulnerability is a use-after-free bug in the Linux kernel's nvmem core component. It occurs in error paths where the function __nvmem_device_put() is called, which may free the underlying memory and other resources. However, the code continues to use the nvmem structure after it has been freed, leading to potential memory corruption or crashes.

Impact Analysis

The use-after-free vulnerability can lead to undefined behavior such as memory corruption, system crashes, or potential exploitation by attackers to execute arbitrary code or cause denial of service on affected Linux systems.
