Description

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - Fix page fault dead lock on mmap-ed hwrng There is a dead-lock in the hwrng device read path.This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng.The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user. 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 service.
