Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/fix/linux/opensuse-su-2026-21058-1 - Platform: Linux - Released: Jun 25, 2026 - Priority: Urgent (Closes CVE-2026-48930, rated Critical) - CVEs: 26, exploited: 0, on CISA KEV: 0 - Vendor advisory: https://osv.dev/vulnerability/openSUSE-SU-2026:21058-1 ## Applies to | Product | Release | Fixed in | |---|---|---| | [nodejs22](https://patchblox.com/security/data/product/linux/nodejs22.md) | opensuse-leap 16.0 | 22.23.0-160000.1.1 | ## CVEs this fix closes | CVE | Priority | Title | CVSS | EPSS | Exploitation | |---|---|---|---:|---:|---| | [CVE-2026-48930](https://patchblox.com/security/data/cve/CVE-2026-48930.md) | Urgent | Node.js and 2 others: Improper Access Control - Generic | 9.8 | 0.0032 | | | [CVE-2026-21710](https://patchblox.com/security/data/cve/CVE-2026-21710.md) | High | A flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received with a header named `__proto__` and the application accesses `req.headersDistinct`. When this occurs, `dest["__proto__"]` resolves to `Object.prototype` rather than `undefined`, causing `.push()` to be called on a non-array. This exception is thrown synchronously inside a property getter and cannot be intercepted by `error` event listeners, meaning it cannot be handled without wrapping every `req.headersDistinct` access in a `try/catch`. * This vulnerability affects all Node.js HTTP servers on **20.x, 22.x, 24.x, and v25.x** | 7.5 | 0.2544 | | | [CVE-2026-48933](https://patchblox.com/security/data/cve/CVE-2026-48933.md) | High | Node.js and 2 others: Integer Overflow | 8.1 | 0.0371 | | | [CVE-2026-48618](https://patchblox.com/security/data/cve/CVE-2026-48618.md) | High | Node.js and 2 others: Improper Handling of Unicode Encoding | 8.1 | 0.0314 | | | [CVE-2026-21637](https://patchblox.com/security/data/cve/CVE-2026-21637.md) | High | HackerOne: CVE-2026-21637 TLS PSK/ALPN Callback Exceptions Bypass Error Handlers | 7.5 | 0.0112 | | | [CVE-2026-27135](https://patchblox.com/security/data/cve/CVE-2026-27135.md) | High | nghttp2 Denial of service: Assertion failure due to the missing state validation | 7.5 | 0.0082 | | | [CVE-2026-12151](https://patchblox.com/security/data/cve/CVE-2026-12151.md) | High | nodejs20: This update for nodejs20 fixes the following issues: - CVE-2025-22150: undici: predictable random values used when d... | 8.1 | 0.0079 | | | [CVE-2026-40170](https://patchblox.com/security/data/cve/CVE-2026-40170.md) | High | ngtcp2: ngtcp2 is a C implementation of the IETF QUIC protocol | 9.0 | 0.0078 | | | [CVE-2026-48619](https://patchblox.com/security/data/cve/CVE-2026-48619.md) | High | Node.js and 2 others: Uncontrolled Resource Consumption | 8.1 | 0.0064 | | | [CVE-2026-48937](https://patchblox.com/security/data/cve/CVE-2026-48937.md) | High | Node.js 22 and 2 others: Uncontrolled Resource Consumption | 7.5 | 0.0057 | | | [CVE-2026-42338](https://patchblox.com/security/data/cve/CVE-2026-42338.md) | High | rh-podman-desktop: ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript | 8.1 | 0.0047 | | | [CVE-2026-21714](https://patchblox.com/security/data/cve/CVE-2026-21714.md) | High | Node.js 14 and 15 others: Missing Release of Memory after Effective Lifetime | 7.5 | 0.0043 | | | [CVE-2026-48615](https://patchblox.com/security/data/cve/CVE-2026-48615.md) | High | Node.js and 2 others: Privacy Violation | 8.1 | 0.0040 | | | [CVE-2026-21713](https://patchblox.com/security/data/cve/CVE-2026-21713.md) | High | Node.js 14 and 15 others: Observable Timing Discrepancy | 7.5 | 0.0037 | | | [CVE-2026-9496](https://patchblox.com/security/data/cve/CVE-2026-9496.md) | High | npm: Versions of the package pacote from 11.2.7 and before 21.5.1 are vulnerable to Denial of Service (DoS) via the addGit... | 7.5 | 0.0035 | | | [CVE-2026-48617](https://patchblox.com/security/data/cve/CVE-2026-48617.md) | High | Node.js 22 and 2 others: Improper Access Control - Generic | 8.2 | 0.0032 | | | [CVE-2026-21717](https://patchblox.com/security/data/cve/CVE-2026-21717.md) | High | A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly degrade performance of the Node.js process. The most common trigger is any endpoint that calls `JSON.parse()` on attacker-controlled input, as JSON parsing automatically internalizes short strings into the affected hash table.
