NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-internal package and not the kernel-debug-modules-internal package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

misc: sgi-gru: remove interrupt-context page-table walks

The GRU TLB miss handler walks a process's page tables without holding page-table locks or a reference to the mapped page. It also uses a kernel page-table accessor on user page tables and supports only PMD-level large mappings on x86-64.

Remove the direct walker. Send interrupt faults directly to user polling mode so the existing call-OS fallback retries them in process context.

Remove the mmap-lock failure statistic that can no longer be incremented.
