In the Linux kernel, the following vulnerability has been resolved:
crypto: xilinx-trng - Remove crypto rng interface
Implementing the crypto rng interface has no purpose, as it isn't used
in practice. It's being removed from other drivers too. Just remove
it. This leaves hwrng, which is actually used.
Tagging with 'Cc stable' due to the bugs that this removes:
-
xtrng trng generate() sometimes returned success even when it didn't fill in all the bytes.
-
It was possible for xtrng trng generate() and xtrng hwrng trng read() to run concurrently and interfere with each other, as the locking code in xtrng hwrng trng read() was broken.
