Later vCPUs on that VM then skip the SVE setup and\nregister with a NULL sve_state, which the guest's first FP access hands\nto sve_load_state().\n\nReturn the error without touching vcpu_features.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/a1b3c788ad31837e348075e93dbba3f447492776","tags":[]},{"url":"https://git.kernel.org/stable/c/bd46b41f412fb81c50bac1a0929ec31320f3a807","tags":[]},{"url":"https://git.kernel.org/stable/c/f0cd8ffae092cc1b9d7cfa9188ed5a88a374adcb","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
