CVE-2026-19888 1 Pgbouncer 1 Pgbouncer 2026-09-23 7.5 High
Missing validation of a mandatory attribute in the SCRAM client-final-message parser in PgBouncer through 1.25.2 allows an unauthenticated remote attacker to crash the process. A malformed message can make the parser report success while leaving a required value unset, which is then dereferenced as a NULL pointer. The crash occurs before any credential is verified, so no valid account is required. Because PgBouncer serves all clients from a single process, this terminates every pooled connection.
CVE-2026-88339 1 Gpac 1 Gpac 2026-09-23 5.5 Medium
A NULL pointer dereference vulnerability exists in the gf_sg_vrml_field_clone() function of GPAC 2d7da22e (26.08-DEV). The vulnerability occurs when cloning a PROTO default SFImage field with a NULL source pointer. An attacker can provide a specially crafted input file that triggers the condition, resulting in application crash and denial of service.

CVE-2026-93312 1 Freedesktop 1 Poppler 2026-09-22 4.3 Medium
A flaw has been found in Freedesktop Poppler 26.07.0. Impacted is the function JBIG2Stream::rewind of the file poppler/JBIG2Stream.cc. This manipulation causes null pointer dereference. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 26.08.0 is recommended to address this issue. Patch name: 5e49250f13b0390edeb3f90eb4c02c9941f97067. Upgrading the affected component is advised.
CVE-2026-86056 1 Notepad-plus-plus 1 Notepad++ 2026-09-22 5.5 Medium
Notepad++ is a free and open-source source code editor. Prior to 8.9.8, the NPPM_SAVESESSION handler in PowerEditor/src/NppBigSwitch.cpp converts lParam to a sessionInfo pointer and dereferences its nbFile, files, and sessionFilePathName members without checking for null. A process running at the same or a higher Windows integrity level on the same desktop can send NPPM_SAVESESSION with a null lParam, immediately terminating Notepad++ and causing denial of service and loss of unsaved documents. This issue is fixed in version 8.9.8.
CVE-2026-69744 1 Microsoft 6 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 3 more 2026-09-22 7.5 High

CVE-2026-92051 1 Mozilla 1 Firefox 2026-09-21 9.1 Critical
Spoofing issue due to invalid pointer in the Graphics component. This vulnerability was fixed in Firefox 156 and Thunderbird 156.
CVE-2026-48521 1 Envoyproxy 1 Envoy 2026-09-21 5.9 Medium
Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's ProdClusterManagerFactory::allocateConnPool dereferences transport_socket_options while selecting an HTTP/3 connection pool without first checking whether the pointer is null. LoadBalancerContext implementations used by synthetic, mirror, health-check, and async-client calls can return no transport-socket options. With auto_config and HTTP/3 enabled, routine traffic reaching one of those contexts can crash an Envoy worker. The relevant scope boundary is that the affected branch requires HTTP/3 in the protocol set and a context that supplies no transport-socket options. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.
CVE-2026-76781 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-09-21 5.5 Medium
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).
CVE-2026-73547 1 Envoyproxy 1 Envoy 2026-09-21 7.5 High
Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's ext_authz filter assumes that a request contains a :path pseudoheader when applying query_parameters_to_set or query_parameters_to_remove from an authorization response. A path-less CONNECT request makes request_headers_->Path() return null, and Filter::onComplete dereferences that pointer while parsing the query string. An unauthenticated downstream client can crash the Envoy process when the filter and authorization response use query-parameter mutation. The relevant scope boundary is that the deployment must accept path-less CONNECT and configure ext_authz query-parameter mutation. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.
CVE-2026-72949 1 Microsoft 11 Windows 11 23h2, Windows 11 23h2, Windows 11 24h2 and 8 more 2026-09-21 7.5 High
Null pointer dereference in Windows SMB Server Network Transport Driver (srvnet.sys) allows an unauthorized attacker to deny service over a network.
CVE-2026-57225 1 Oisf 1 Suricata 2026-09-21 3.3 Low
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, src/datasets-context-json.c assumes that a configured JSON or NDJSON dataset value_key resolves to a string. A trusted or untrusted dataset or rule feed containing a non-string value for that key can cause a NULL pointer dereference during startup, configuration test mode, or rule reload, crashing Suricata before traffic processing. This issue is fixed in version 8.0.6.
CVE-2026-92032 1 Mozilla 1 Firefox 2026-09-21 9.6 Critical
Sandbox escape due to invalid pointer in the Graphics component. This vulnerability was fixed in Firefox 156, Firefox ESR 140.16, Firefox ESR 153.3, Thunderbird 156, Thunderbird 140.16, and Thunderbird 153.3.
CVE-2026-90828 1 Gnu 1 Binutils 2026-09-21 5.3 Medium
A security flaw has been discovered in GNU Binutils 2.47. This vulnerability affects the function elf_orphan_compatible of the file ld/ldelf.c of the component ELF Orphan Section Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.
CVE-2026-85150 2 Freedesktop, Redhat 2 Gstreamer, Enterprise Linux 2026-09-21 7.5 High
A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity.
