What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include this patch to resolve the issue. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended mitigation. No additional workarounds or mitigations are indicated.
Description
CVE-2024-53196 is a vulnerability in the Linux kernel's KVM subsystem for arm64 architecture. It involves improper handling of aborted MMIO instructions where KVM incorrectly retires the instruction despite a pending synchronous external abort. This can cause kernel warnings and potentially impact system stability. The issue arises from a bug in the KVM user API (UAPI) handling of MMIO aborts. The vulnerability has a medium severity score of 5.5 and does not affect confidentiality or integrity but impacts availability.
