Description
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.
