In the Linux kernel, the following vulnerability has been resolved:
crypto: sun8i-ce - Remove crypto_rng interface
Since the crypto_rng interface for hardware PRNGs is unused and is
redundant with hwrng and the actual Linux RNG, it's being phased out.
Most drivers for it were already removed. Go ahead and remove the
sun8i-ce support which is one of the only remaining ones.
Note that the sun8i-ce support for hwrng remains in place. That is the
interface that actually matters.
As usual for crypto_rng, this driver was also buggy: its ->generate()
function had a use-after-free vulnerability due to using
wait_for_completion_interruptible_timeout() without handling shutting
down the DMA operation if a signal is sent. There's no point in fixing
this separately only to remove the code anyway, so this commit is marked
with Fixes and Cc stable.
