Description OSIDB Bzimport 2024-07-30 08:41:10 UTC 
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.
