CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's s390/zcrypt component, specifically in how it handles CCA AES cipher key requests. If the length of the key token exceeds the allocated space in the parameter block, it could lead to potential memory corruption or denial of service. Organizations using Linux systems with s390 architecture should prioritize addressing this issue to mitigate risks associated with cryptographic operations.
Original NVD Description
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.
