CVE-2026-89909
In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Free init resources if kvm_init() fails kvm_loongarch_init() calls kvm_loo
In the Linux kernel, the following vulnerability has been resolved:
LoongArch: KVM: Free init resources if kvm_init() fails
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().
