Created: Feb 28, 2024

Resolved Date: Mar 21, 2024
Found In Version: 10.19.45.1
Severity: Standard
Applicable for: Wind River Linux LTS 19
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:
KVM: VMX: Disable preemption when probing user return MSRs
Disable preemption when probing a user return MSR via RDSMR/WRMSR. If
the MSR holds a different value per logical CPU, the WRMSR could corrupt
the host's value if KVM is preempted between the RDMSR and WRMSR, and
then rescheduled on a different CPU.
Opportunistically land the helper in common x86, SVM will use the helper
in a future commit.
