CVE-2026-80708

A flaw was found in the Linux kernel's s390/zcrypt module. During the clear key to secure key token import process, an internal buffer used by the ipcprbhelper function was not properly scrubbed after use. This oversight could leave sensitive clear key material in memory. A local attacker could...

CVE-2026-80709

A flaw was found in the Linux kernel's s390/zcrypt component. An incorrect upper limit check for the domain value when processing an EP11 Cryptographic Coprocessor Request Block CPRB can allow a local user on custom device nodes to access heap memory. This could lead to information disclosure or...
