4 CVE

  1. CVE-2026-76781 5.5 Moyenne

    Red Hat Hardened Images · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS).

  2. CVE-2026-87742 7.5 Élevée

    Red Hat build of Quarkus 3.27.5.SP2 · Red Hat build of Quarkus 3.33.3.SP2 · Red Hat Exploit Intelligence · Red Hat Enterprise Linux AI (RHEL AI) 3

    A flaw was found in quarkus-websockets-next. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by streaming messages over a single connection faster than the application can process them. Due to unbounded message buffering and a lack of read backpressure, this rapidly exhausts heap space, leading to a java.lang.OutOfMemoryError that crashes the Java Virtual Machine (JVM).

  3. CVE-2026-92925 7.1 Élevée

    Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions · Red Hat Enterprise Linux 9.6 Extended Update Support · Red Hat Pen Drive Powered by Red Hat Lightspeed

    A flaw was found in Redis community. The cluster bus packet parser, responsible for handling PING, PONG, and MEET packets, fails to properly validate string-carrying extensions for null-termination. This oversight allows a remote attacker to craft a malicious packet, leading to an out-of-bounds read when the packet's payload is processed. Successful exploitation of this vulnerability could result in the disclosure of sensitive information or a remote denial of service (DoS).

  4. CVE-2026-86320 7.8 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 8.8 Telecommunications Update Service

    A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true. An attacker who can provide a malicious source containing a Git post-applypatch hook can cause the hook to execute on the host during the build process, resulting in arbitrary code execution with the privileges of the user running flatpak-builder.
