Linux kernel versions 5.10-rc4, 5.4.66, and 5.9.8 are impacted and a patch was merged on December 3 to tackle the bug. Users are urged to update their builds to later versions.

In particular, memory areas used as input and/or output are isolated from the rest of the kernel and surrounded by guard pages. Without arch hooks, this common base provides weak isolation.

The kernel works to keep some spare pages around at all times, so the memory stress must be severe before a single-page allocation will fail.

Specifically, they’re updating the Windows kernel in-memory with the Gigabyte driver, according to the research – and the kernel accepts it as a “patch” thanks to the signed certificate.

New Linux code helps the kernel keep track of memory holding data for the GPU. The management of video hardware has long been an area of weakness in the Linux system (and free operating systems in ...

KDP offers the makers of driver software that runs in the Windows kernel, and the OS code itself, "the ability to mark some kernel memory containing sensitive information as read-only protected".
