In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
LoongArch: KVM: Free init resources if kvm_init() fails<\/p>\n
kvm_loongarch_init() calls kvm_loongarch_env_init() to allocate the
\nper-CPU kvm_context (vmcs) and kvm_loongarch_ops and to register the
\nperf callbacks, and then calls kvm_init(). If kvm_init() fails its
\nresult is returned directly, but since module_init() does not run the
\nmodule_exit() stuff on failure, so kvm_loongarch_env_exit() is never
\ncalled and those resources are leaked.<\/p>\n
So call kvm_loongarch_env_exit() when kvm_init() fails, matching the
\nteardown-on-failure pattern used by riscv_kvm_init().<\/p>\n","protected":false},"excerpt":{"rendered":"
