Delta files are significantly smaller than full OCI archives because they exclude layers already present on the target system and use binary diffs (tar-diff) for changed layers.\n\nSecurity Fix(es):\n\n* encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818)\n\n* crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references (CVE-2026-97031)\n\nBug Fix(es) and Enhancement(s):\n\n* Update oci-delta to v0.3.1 for Rocky Linux 10.3.z async release (JIRA:Rocky Linux-290036)\n\nFor more details about
