Affected files ============== The file(s) affected by this issue are: arch/loongarch/kvm/vcpu.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/15469ba0284c7cc01c38493391e9e73b918833c4 https://git.kernel.org/stable/c/efe27b19a15c384cad7c80de399f3107ab070e6d https://git.kernel.org/stable/c/d4574547e04a47ad498149576f65b84475ea6f4c https://git.kernel.org/stable/c/09b318ab77b7a4fc9987fd98d1525fc55ddc2617
