https://notcve.org/view.php?id=CVE-2024-40989
12 Jul 2024 — 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 co... • https://git.kernel.org/stable/c/e5a35635464bc5304674b84ea42615a3fd0bd949 • CWE-825: Expired Pointer Dereference •
