CVE-2026-68452
In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Validate length for CCA AES cipher key requests cca_cipher2protkey() derives the copy length for the CPRB parameter block directly from the length field in the key token. Reject the request early if the token length exceeds the available space in the parameter block.
