What is CVE-2026-45854?

CVE-2026-45854 is a medium-severity vulnerability in Linux kernel, published on 27 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

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.

Which versions are affected by CVE-2026-45854?

It affects 1 product.

Products include Linux kernel.

How do I fix CVE-2026-45854?

Apply the vendor's patch.
