CVE-2026-98648

A flaw was found in the Linux kernel's IBM s390 Ultravisor subsystem. When searching stored secrets on systems holding more than 85 secrets, the kernel incorrectly references the total secret count instead of the number of items stored in the current memory page. A local user can exploit this...

CVE-2026-64369

A flaw was found in the Linux kernel, specifically within the s390 architecture. When the system attempts to read unaligned data that spans across memory pages, it can trigger exceptions. For memory pages designated for secure execution by the Ultravisor, the exception handling mechanism does not...

CVE-2026-64369

CVE-2026-64369 affects the Linux kernel s390 architecture . The function load_unaligned_zeropad() reads eight bytes from unaligned addresses that may cross page boundaries. For pages donated to the Ultravisor for secure execution, the do_secure_storage_access() exception handler does not correctl...

CVE-2026-31568

A flaw was found in the Linux kernel. This vulnerability, located in the s390/mm component, is due to missing secure storage access fixups for memory donated to the Ultravisor. When secure storage access exceptions occur for such memory, the kernel can enter an unresolvable loop. This can lead to...
