Abstract: A capability management method and apparatus, a computer device, and the like relate to permission management of a kernel object in an operating system, for example, permission management of a kernel object in a microkernel architecture. In the method, two types of information are stored in a capability node of a capability owner: information used to indicate that a capability is granting and information used to indicate a granted capability. A capability association relationship between a grantor and a grantee is established by recording the two types of information, so that capability copying is avoided in a capability granting procedure, and capability deletion is avoided in a procedure of rejecting a capability by the grantee, thereby ensuring a deterministic latency while implementing capability revocation and granting. The method may be applied to a smartphone system, an unmanned driving system, or the like.
