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 concerns the Linux kernel on s390 where load_unaligned_zeropad() may read eight bytes from unaligned addresses and cross page boundaries. When memory is donated to Ultravisor for secure execution, do_secure_storage_access() can mis-handle exceptions, potentially causing an endless ...

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...
