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.
