In the Linux kernel, the following vulnerability has been resolved: s390: Revert support for DCACHE_WORD_ACCESS load_unaligned_zeropad() reads eight… (CVE-2026-64369)CVE-2026-64369 0 A vulnerability in the Linux kernel's s390 architecture involves the load_unaligned_zeropad() function, which reads eight bytes from unaligned addresses and may cross page boundaries. When pages are donated to the Ultravisor for secure execution, exceptions triggered by these reads are not handled correctly by the do_secure_storage_access() exception handler, potentially causing an endless exception loop. The issue was temporarily mitigated by reverting the load_unaligned_zeropad() support until a proper fix is developed. The function's implementation itself is correct; the revert is a workaround for incomplete exception handling in secure storage access.
