What to do
AI-suggested
A fix has been implemented in the Linux kernel to wipe all copies of protected- and secure-keys from the stack, including in error scenarios. Users should update to the fixed kernel versions once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel s390 architecture involving the handling of protected- and secure-keys has been addressed. The issue concerns residual copies of these keys remaining on the stack, which should only be visible to the calling process. The fix ensures that all copies of protected- or secure-keys are wiped from the stack, including in error cases.
