  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: qcom-rng - Remove crypto_rng interface  qcom-rng.c exposes the same hardware through two completely separate interfaces, crypto_rng and hwrng.  However, the implementation of this is buggy because it permits generation operations from these interfaces to run concurrently with each other, accessing the same registers.  That is, qcom_rng_generate() synchronizes with itself but not with qcom_hwrng_read().  This results in potential repetition of output from the RNG, output of non-random values, etc.  Fortunately, there\u0027s actually no point in hardware RNG drivers implementing the crypto_rng interface.  It\u0027s not actually used by anything besides the \u0022rng\u0022 algorithm type of AF_ALG, which in turn is not actually used in practice.  Other crypto_rng hardware drivers are likewise being phased out, leaving just the hwrng support.  Thus, remove it to simplify the code and avoid conflict (and confusion) with the hwrng interface which is the one that actually matters.",
