CVE-2022-49286

CVE-2022-49286 is tied to a Linux kernel TPM space fix: tpm2_del_space() was missing proper teardown after series conversion, leading to a tiny race where chip->tpm_mutex could be dereferenced if the space flush occurs after removal. The accepted mitigation is to convert tpm2_del_space() to us...
