Frequently Asked Questions
1
What condition triggers the use-after-free?
The issue occurs when the driver's generate operation is interrupted by a signal while it is waiting for DMA completion. The interrupted path does not shut down the DMA operation before freeing the relevant resources.
2
Does removing this interface eliminate sun8i-ce hardware random-number support?
No. The sun8i-ce hwrng support remains in place. The removed crypto_rng interface was redundant with hwrng and the Linux RNG.
