efi: fix NULL-deref in init error path
ソース: NVD (National Vulnerability Database)
脆弱性説明
In the Linux kernel, the following vulnerability has been resolved: efi: fix NULL-deref in init error path In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated. Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer.
