However, if the BPF LSM is not explicitly enabled at boot time (e.g. omitted from the \"lsm=\" boot parameter), lsm_prepare() is never executed for the BPF LSM.  Consequently, the BPF inode security blob offset (bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains at its default compiled size of 8 bytes instead of being updated to a valid offset past the reserved struct rcu_head (typically 16 bytes or more).  When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGE map, bpf_inode() evaluates inode->i_security + 8. This erroneously aliases the struct rcu_head.func callback pointer at the beginning of the inode->i_security blob. During subsequent map element cleanup or inode destruction, writing NULL to owner_storage clears the queued RCU callback pointer. When rcu_do_batch() later executes the queued callback, it attempts an instruction fetch at address 0x0, triggering an immediate kernel panic.  Fix this by introducing a global bpf_lsm_initialized boolean flag marked with __ro_after_init. Set this flag to true inside bpf_lsm_init() when the LSM framework successfully registers the BPF LSM. Gate map allocation in inode_storage_map_alloc() on this flag, returning -EOPNOTSUPP if the BPF LSM is in turn uninitialized.  This fail-fast approach prevents userspace from allocating inode storage maps when the supporting BPF LSM infrastructure is absent, avoiding zombie map states.",null,[],[],[],[14],{"_key":15},"CVE-2026-64192",[],[],[],"2026-07-20T17:18:22.367Z","2026-07-21T08:48:23.157559742Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2026-64192",[27],"osv_debian",[29],"Advisory",[],[],[],[34],{"ecosystem":35,"name":36,"vendor":37,"product":36,"cpe_part":9,"purl_type":38,"purl_namespace":37,"purl_name":36,"source":9,"versions":39},"Debian","linux","debian","deb",[40,44,45,46],{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9}]
