Intel Processor Flaw Affects Nearly Every Modern Device

According to a blog post published yesterday, the core team of Linux kernel development has prepared a critical kernel update without releasing much information about the vulnerability.

Multiple researchers on Twitter confirmed that Intel processors (x86-64) have a severe hardware-level issue that could allow attackers to access protected kernel memory, which primarily includes information like passwords, login keys, and files cached from disk.

The security patch implements kernel page-table isolation (KPTI) to move the kernel into an entirely separate address space and keeps it protected and inaccessible from running programs and userspace, which requires an update at the operating system level.
