LoongArch: KVM: Free init resources if kvm_init() fails
Published Sep 16, 2026
No CVSS score
EPSS 0.21%
Description
kvm_loongarch_init() calls kvm_loongarch_env_init() to allocate the per-CPU kvm_context (vmcs) and kvm_loongarch_ops and to register the perf callbacks, and then calls kvm_init(). If kvm_init() fails its result is returned directly, but since module_init() does not run the module_exit() stuff on failure, so kvm_loongarch_env_exit() is never called and those resources are leaked.
So call kvm_loongarch_env_exit() when kvm_init() fails, matching the teardown-on-failure pattern used by riscv_kvm_init().
