Andrii Nakryiko 62039c30c1 bpf: Initialize storage pointers to NULL to prevent freeing garbage pointer ... Local storage array isn't initialized, so if cgroup storage allocation fails for BPF_CGROUP_STORAGE_SHARED, error handling code will attempt to free uninitialized pointer for BPF_CGROUP_STORAGE_PERCPU storage type. Avoid this by always initializing storage pointers to NULLs.
