Doc Text:
A flaw was found in the Linux kernel's EIP93 cryptographic accelerator driver. This vulnerability occurs because the driver attempts to unregister all cryptographic algorithms, even those not supported by the hardware. This incorrect handling can lead to a system panic, effectively causing a Denial of Service (DoS) on platforms where not all EIP93 options are implemented in silicon.

Description OSIDB Bzimport 2026-05-27 15:13:40 UTC 
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.
