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.
