    High [CVE-2026-33818] Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

    CVE-2026-33818Source published Source updated

    Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures. A flaw was found in the `encoding/asn1` package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One (ASN.1) structure, leading to excessive recursion during the `Unmarshal` operation. This could result in stack exhaustion and a Denial of Service (DoS) condition. An attacker can provide a malformed ASN.1 structure, causing excessive recursion during unmarshalling and leading to stack exhaustion, which can render the service unavailable. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-776. Affected products named by the advisory: Red Hat Enterprise Linux 10.0 Extended Update…
