  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: loongson - Remove broken and unused loongson-rng  The loongson-rng rng_alg has several vulnerabilities, including not providing forward security, and a use-after-free bug due to the use of wait_for_completion_interruptible().  Meanwhile, the rng_alg framework doesn\u0027t really have any purpose in the first place other than to access the software algorithms crypto/drbg.c and crypto/jitterentropy.c.  Hardware-specific rng_algs have no in-kernel user, and unlike hwrng there\u0027s no feed into the actual Linux RNG.  As such, there\u0027s really no point to this code.  There are of course other rng_alg drivers that are similarly unused, but they\u0027re similarly in the process of being phased out, e.g. https://lore.kernel.org/r/20260529193648.18172-1-ebiggers@kernel.org and https://lore.kernel.org/r/20260529220430.34135-1-ebiggers@kernel.org  Given that, there\u0027s no point in fixing forward these vulnerabilities, and it makes much more sense to simply roll back the addition of this driver.  If this platform provides TRNG (not PRNG) functionality, it could make sense to add a hwrng driver, but it would be quite different.",
