Descriptions
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Disassociate vcpus from redistributor region on teardown
When tearing down a redistributor region, make sure we don't have
any dangling pointer to that region stored in a vcpu.
A vulnerability was found in the Linux kernel's KVM for ARM64 within the vgic-init.c, vgic-mmio-v3.c, and vgic.h files. The virtual vCPUs may retain dangling pointers in a redistributor region after they have been torn down, leading to potential memory corruption.
