kernel: hwrng: core - Fix page fault dead lock on mmap-ed hwrng

A vulnerability was found in the hwrng component of the Linux kernel, which caused a deadlock when reading from /dev/hwrng into memory and mmap-ed from /dev/hwrng. This issue is triggered by a recursive read during a page fault and allows a local, authenticated attacker to cause a denial of servi...
