CVE-2026-73583 is an unsafe deserialization flaw in sblim-sfcb's provider-manager IPC operation-header parsing. A malformed OperationHdr in a crafted IPC message can cause out-of-bounds memory access while the provider-manager processes the message. The resulting memory-safety failure can terminate the provider-manager and may permit limited unintended information disclosure.
