## Overview

In the Linux kernel, the following vulnerability has been resolved:

s390/pkey: Wipe copies of protected- and secure-keys

Although the clear-key of neither protected- nor secure-keys is
accessible, this key material should only be visible to the calling
process. So wipe all copies of protected- or secure-keys from stack,
even in case of an error.

## Affected

- `Linux >= e80d4af0a320972aac58e2004d0ba4e44ef4c5c7 < 7d5711e03cefd59da4d198ca02d4f8238ba1105c`
- `Linux >= e80d4af0a320972aac58e2004d0ba4e44ef4c5c7 < c746f7ced4ad88ee48d0b6c92710e4674403185b`
- `Linux >= e80d4af0a320972aac58e2004d0ba4e44ef4c5c7 < f2ebdadd85af4f4d0cae1e5d009c70eccc78c207`
- `Linux 4.11`
