SUSE CVE-2026-68453

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Fix buffer over-read in ccacipher2protkey Add validation of both the actual key buffer size and token length fields in all the ccachecksectoken functions. Additionally check in ccagencipherkey for possible underflow...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Eliminated the possibility of speculative memory reading. The domain value is extracted from a given CCA or EP11 ioctl struct when a CPRB is about to be sent. Therefore, this is a user-controlled value. Under certain...

CVE-2026-74466

A flaw was found in the Linux kernel's s390/zcrypt component. Under specific conditions, a user-controlled domain value, derived from CCA or EP11 ioctl structures, is used as an array index without a proper speculation barrier. This oversight could allow for speculative memory reads, potentially...

CVE-2026-74466

The CVE-2026-74466 vulnerability concerns the Linux kernel’s s390/zcrypt path. A domain value is extracted from a CCA or EP11 ioctl struct and, under certain conditions (custom device node, administrative load), is used as an array index after bounds checking without a speculation barrier. This c...

CVE-2026-68451

A flaw was found in the Linux kernel's s390 zcrypt module. The ccaecc2protkey function, responsible for handling Common Cryptographic Architecture CCA Elliptic Curve Cryptography ECC private key requests, does not properly validate the length of the key token. This allows a local attacker to...

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...
