[PATCH openEuler-22.03-LTS-SP1] x86/mtrr: Check if fixed MTRRs exist before saving them
by Zeng Heng 12 Sep '24

12 Sep '24

From: Andi Kleen <ak(a)linux.intel.com> stable inclusion from stable-v5.10.224 commit 450b6b22acdaac67a18eaf5ed498421ffcf10051 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOXYQ CVE: CVE-2024-44948 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 919f18f961c03d6694aa726c514184f2311a4614 upstream. MTRRs have an obsolete fixed variant for fine grained caching control of the 640K-1MB region that uses separate MSRs. This fixed variant has a separate capability bit in the MTRR capability MSR. So far all x86 CPUs which support MTRR have this separate bit set, so it went unnoticed that mtrr_save_state() does not check the capability bit before accessing the fixed MTRR MSRs. Though on a CPU that does not support the fixed MTRR capability this results in a #GP. The #GP itself is harmless because the RDMSR fault is handled gracefully, but results in a WARN_ON(). Add the missing capability check to prevent this.
