CVE-2026-68452

A flaw was found in the Linux kernel's s390/zcrypt component. This vulnerability arises from insufficient validation of the length of CCA AES cipher key requests. A local attacker could exploit this by providing a specially crafted key token, which may lead to a buffer overflow. This could result...
