      <title>CVE-2026-42530 — NGINX Open-Source ngx_http_v3_module vulnerability</title>
      <link>https://db.gcve.eu/vuln/cve-2026-42530</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; F5 NGINX Open Source, Red Hat Hardened Images, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Lightspeed proxy 1&lt;/p&gt;
&lt;p&gt;NGINX Open Source has a vulnerability in the ngx_http_v3_module module. When NGINX Open Source is configured to use the HTTP/3 QUIC module, a remote unauthenticated attacker along with conditions beyond their control can use a specially crafted HTTP/3 session to reopen a QPACK encoder stream. This may cause a Use-after-Free in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.&lt;/p&gt;
&lt;p&gt;Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.&lt;/p&gt;</description>
