Описание
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: account pKVM reclaim against the VM mm
Protected guest faults charge long term pins to the VM's mm. Teardown
can run later from file release, where current->mm may be unrelated.
Drop the charge from kvm->mm instead.
A flaw was found in the Linux kernel's Kernel-based Virtual Machine (KVM) for arm64 architectures. This vulnerability involves an issue with memory accounting for protected guest faults. During the teardown process, the system may incorrectly manage long-term memory pins, potentially leading to resource management inconsistencies within the virtual machine's memory. This could affect system stability or resource availability.
