Some enhancements to the Random Number Generator (RNG) are available in UEK 8 with upstream changes that are included from v5.15 to v6.12. Most notably, RNG has switched from the SHA1 hash algorithm to the faster and more secure BLAKE2s algorithm.

Also, the getrandom() system call is now implemented in the kernel's virtual dynamic shared object (vDSO) area. This implementation improves performance when obtaining random number data by removing the need to switch from a user space context into the kernel context.
