What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
