CVE-2026-98475: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: s390/cmf: Fix virtual vs physical address confusion The measurement block address is an absolute address. Define the associated schib_config and schib fields as dma64_t to enable automatic detection of incorrect assignments. Also add the missing virt_to_dma64() translation. Without this fix, a wrong address will be used by firmware when storing extended format channel measurement data on kernels built with CONFIG_RANDOMIZE_IDENTITY_BASE=y.
