What to do
AI-suggested
A fix has been implemented in the Linux kernel to wipe sensitive clear-key data on failure in the s390 pkey subsystem. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's s390 architecture pkey handling was resolved by ensuring that copies of clear-key structures are wiped on failure. This involves wiping all sensitive data from the stack for all IOCTL operations that convert a clear-key into a protected or secure key.
