Official description

In the Linux kernel, the following vulnerability has been resolved: crypto: inside-secure/eip93 - unregister only available algorithm EIP93 has an options register. This register indicates which crypto algorithms are implemented in silicon. Supported algorithms are registered on this basis. Unregister algorithms on the same basis. Currently, all algorithms are unregistered, even those not supported by HW. This results in panic on platforms that don't have all options implemented in silicon.
