  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: sun4i-ss - Remove insecure and unused rng_alg  Remove sun4i_ss_rng, as it is insecure and unused:  - It has multiple vulnerabilities.  sun4i_ss_prng_seed() is missing   locking and has a buffer overflow.  sun4i_ss_prng_generate() fails to   fill the entire buffer with cryptographic random bytes, because it   rounds the destination length down and also doesn\u0027t actually wait for   the hardware to be ready before pulling bytes from it.  - No user of this code is known.  It\u0027s usable only theoretically via the   \u0022rng\u0022 algorithm type of AF_ALG.  But userspace actually just uses the   actual Linux RNG (/dev/random etc) instead.  And rng_algs don\u0027t   contribute entropy to the actual Linux RNG either.  (This may have   been confused with hwrng, which does contribute entropy.)  The sun4i_ss_prng_seed() buffer overflow was reported by Tianchu Chen and discovered by Atuin - Automated Vulnerability Discovery Engine  There\u0027s no point in fixing all these vulnerabilities individually when this is unused code, so let\u0027s just remove it.",
