CVE-2026-80544

A flaw was found in the Linux kernel's s390/zcrypt component. The zcryptmsgtype6sendep11cprb function, responsible for handling EP11 CPRB Coprocessor Request Block domains, uses fragile struct overlays. This approach lacks proper ASN.1 Abstract Syntax Notation One encoding validation and bounds...

CVE-2026-80543

A flaw was found in the Linux kernel's s390/zcrypt component. When copying user-space messages into a kernel buffer, the system fails to properly pad the message to a 4-byte length. This oversight can lead to up to three bytes of uninitialized kernel memory being exposed to the crypto card...

CVE-2026-80545

A flaw was found in the Linux kernel's s390/zcrypt component. This vulnerability stems from insufficient input validation in the xcrbmsgtotype6ep11cprbmsgx function when handling EP11 Cryptographic Coprocessor Request Block CPRB messages. A local attacker could exploit this by crafting a maliciou...

CVE-2026-80546

A flaw was found in the Linux kernel's s390/zcrypt component, specifically within the xcrbmsgtotype6cprbmsgx function. This vulnerability is due to insufficient input validation, which can lead to integer overflows during memory allocation and arithmetic operations, as well as a lack of minimum...
