  1. CVE-2026-19879 5.3 Moyenne

    Red Hat build of Apache Camel for Spring Boot 4 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in Undertow, an HTTP server, within its HTTP response header writing path. The `writeString()` method performs a silent narrowing cast from 16-bit Unicode characters to 8-bit bytes when writing HTTP response header values. A remote attacker can exploit this by supplying specific Unicode characters in user-controlled input that an application places into response headers. This can lead to the truncation of these characters into ASCII control characters or special symbols, potentially resulting in limited integrity impact or information disclosure if the application does not properly sanitize user input.

  2. CVE-2026-18663 5.9 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function frees the parsed controls array on the Session Tracking critical-control rejection path without clearing the SLAPI_REQCONTROLS pblock slot. Operation teardown then frees the same pointer again, causing a double-free. An unauthenticated remote attacker can trigger this with a single BIND request carrying a critical Session Tracking control, resulting in heap corruption and potential denial of service.

  3. CVE-2026-71218 5.3 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in iperf3. A remote unauthenticated attacker can exploit a vulnerability in the `JSON_read()` function, which accepts a peer-controlled message length and allocates memory without an upper bound. This allows the attacker to trigger excessive memory consumption, leading to a Denial of Service (DoS) through memory exhaustion, severe slowdown, or termination of the iperf3 service.

  4. CVE-2026-19391 6.5 Moyenne

    Red Hat Pen Drive Powered by Red Hat Lightspeed · Red Hat Certification Program for Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 9

    A flaw was found in insights-core where the password redaction layer fails to recognize credentials not keyed under the literal string 'password'. This allows SSSD LDAP bind passwords (ldap_default_authtok) and Pacemaker fence device credentials to be included in cleartext in archives uploaded to console.redhat.com.

  5. CVE-2026-19411 3.9 Faible

    Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A NULL pointer vulnerability has been found in the the shim application of dp.c library. A missing NULL pointer could allow attackers to perform a denial of service attack on a system that uses shim application for UEFI bootloader.

  6. CVE-2026-63623 5.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in libvirt. During storage volume clone or convert operations, newly created volume images were temporarily world-readable. This was caused by the `qemu-img` utility running with overly permissive file creation settings, allowing any local user to read the full guest disk contents. This vulnerability could lead to sensitive information disclosure from guest virtual machines.

  7. CVE-2026-19404 6.5 Moyenne

    Red Hat Directory Server 11 · Red Hat Directory Server 12 · Red Hat Directory Server 13 · Red Hat Enterprise Linux 10

    A flaw was found in 389 Directory Server. The CleanAllRUV and Abort CleanAllRUV replication-maintenance extended operations perform no authorization check, allowing an unauthenticated remote attacker to invoke them when nsslapd-allow-anonymous-access is enabled (the default), or any authenticated low-privilege user to invoke them otherwise. This allows removal of a replica ID from replication metadata, purging of changelog records, and interruption of administrator-initiated cleanup, which can leave replication inconsistent or unavailable.

  8. CVE-2026-61477 2.3 Faible

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root.

  9. CVE-2026-18938 6.2 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in p11-kit. A local attacker, or one with equivalent access to a reachable RPC channel, could exploit an integer overflow vulnerability. By sending specially crafted messages, the attacker can cause the system to miscalculate memory allocation for nested attributes. This leads to a memory corruption issue, specifically a heap out-of-bounds write, which can crash the p11-kit RPC parsing process, resulting in a Denial of Service (DoS). This vulnerability is only exploitable on 32 bit systems.

  10. CVE-2026-53175 9.8 Critique

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

    In the Linux kernel, the following vulnerability has been resolved: inet: frags: fix use-after-free caused by the fqdir_pre_exit() flush On netns teardown, fqdir_pre_exit() walks the fqdir rhashtable and flushes every fragment queue that is not yet complete using inet_frag_queue_flush(). That helper frees all the skbs queued on the fragment queue but does not set INET_FRAG_COMPLETE, and leaves q->fragments_tail and q->last_run_head pointing at the freed skbs. The queue itself stays in the rhashtable. fqdir_pre_exit() first lowers high_thresh to 0 to stop new queue lookups, but it cannot stop a fragment that already obtained the queue through inet_frag_find() earlier and stalled just before taking the queue lock. Once that fragment resumes after the flush and takes the queue lock, it passes the INET_FRAG_COMPLETE check and then dereferences the freed fragments_tail. inet_frag_queue_insert() reads FRAG_CB() and ->len of that pointer and, on the append path, writes ->next_frag, causing a slab use-after-free. IPv6, nf_conntrack_reasm6 and 6lowpan reassembly share the same flush path and are affected as well. Reset rb_fragments, fragments_tail and last_run_head in inet_frag_queue_flush() so a flushed queue no longer points at the freed skbs. A fragment that resumes after the flush and takes the queue lock then finds an empty queue and starts a new run instead of dereferencing the freed fragments_tail. ip_frag_reinit() already performed this reset after its own flush, so drop the now duplicate code there.
