CVE-2025-59150 1 Oisf 1 Suricata 2026-10-12 N/A 7.5 HIGH
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Version 8.0.0's usage of the tls.subjectaltname keyword can lead to a segmentation fault when the decoded subjectaltname contains a NULL byte. This issue is fixed in version 8.0.1. To workaround this issue, disable rules using the tls.subjectaltname keyword.
CVE-2026-13213 2026-10-12 N/A 5.3 MEDIUM
The Hearing Access Service (HAS) GATT server in subsys/bluetooth/audio/has.c installs a connection-callback set unconditionally via BT_CONN_CB_DEFINE, so security_changed() runs for every connection that establishes security even before the application has called bt_has_register(). The service attribute pointers hearing_aid_features_attr, preset_control_point_attr, and active_preset_index_attr remain NULL until bt_has_register() resolves them and sets has.registered. With CONFIG_BT_SETTINGS, settings_set_cb() restores each bonded client's persisted context at boot and unconditionally sets context->flags to BONDED_CLIENT_INIT_FLAGS (non-zero). When a previously bonded peer reconnects and re-establishes security during the startup window before bt_has_register() has been called, security_changed() sees the non-zero flags and schedules notify_work_handler, which calls bt_gatt_is_subscribed() with a still-NULL attribute pointer. That triggers an assertion (__ASSERT(attr, ...) in bt_gatt_is_subscribed()), or a NULL dereference of attr->uuid when assertions are compiled out. The result is a remotely triggerable (Bluetooth, adjacent) crash of the HAS peripheral. Exploitation requires the peer to have previously bonded with the device and to reconnect within the boot-time race window before the application registers the service; a peer that reconnects persistently can prolong the outage. Impact is denial of service only, with no memory corruption or information disclosure. The fix adds an early if (!has.registered) { return; } guard in security_changed(), so no notification work is scheduled until the GATT service is registered and its attribute pointers are valid.
CVE-2026-55371 2026-10-12 N/A N/A
OpenEXR is the reference implementation and specification for the EXR high-dynamic-range image file format, widely used in the motion picture industry. Versions 3.4.0 through 3.4.12 contain a NULL pointer dereference in the OpenEXRCore function exr_attr_set_bytes(). The public setter validates the top-level exr_attr_bytes_t value pointer but does not verify that the nested type_hint pointer is non-NULL when hint_length is greater than zero. When a caller supplies a positive hint_length together with a NULL type_hint, exr_attr_bytes_create() allocates a destination type-hint buffer and then copies from the NULL source pointer, causing a deterministic crash. The flaw is reachable through the public OpenEXRCore C API and results in a denial of service. The issue is fixed in version 3.4.13.
CVE-2025-59537 1 Argoproj 1 Argo Cd 2026-10-12 N/A 7.5 HIGH
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions 1.2.0 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.7 and 3.0.18 are vulnerable to malicious API requests which can crash the API server and cause denial of service to legitimate clients. With the default configuration, no webhook.gogs.secret set, Argo CD’s /api/webhook endpoint will crash the entire argocd-server process when it receives a Gogs push event whose JSON field commits[].repo is not set or is null. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.
CVE-2025-10823 2026-10-11 1.7 LOW 3.3 LOW
A vulnerability was found in axboe fio up to 3.41. This affects the function str_buffer_pattern_cb of the file options.c. Performing manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been made public and could be used.
CVE-2026-107169 2026-10-10 N/A 6.2 MEDIUM
A flaw was found in m17n-lib. An attacker could provide specially crafted or truncated UTF-8 input to trigger an unhandled null pointer dereference during text processing. This issue causes the application to crash unexpectedly, resulting in a Denial of Service (DoS).
CVE-2026-104114 2026-10-09 N/A N/A
A NULL pointer dereference in the illumos Network Auto-Magic daemon (nwamd) allows a local user to crash the daemon. nwamd_door_switch() in usr/src/cmd/cmd-inet/lib/nwamd/door_if.c writes to the caller's request structure before checking that a request was supplied, and before checking the caller's credentials. Because the nwamd door at /etc/svc/volatile/nwam/nwam_door is accessible to all local users, an unprivileged user can issue a door_call() with no argument data to crash nwamd; repeated calls place the svc:/network/physical:nwam service into maintenance, stopping automatic network configuration. nwamd runs only when svc:/network/physical:nwam is enabled, which is not the default. The flaw has existed since 2010 (illumos-gate commit 6ba597c5), and affects any illumos distribution prior to illumos-gate commit 0f1064d9.
CVE-2026-108063 2026-10-09 N/A 5.5 MEDIUM
A flaw was found in libhangul. When parsing Hanja dictionary files, the library fails to verify that an entry contains a valid value alongside its key. By providing a specially crafted dictionary file to an application that queries it, an attacker can trigger an unexpected application crash, resulting in a Denial of Service (DoS).
CVE-2026-107778 2026-10-09 N/A 6.5 MEDIUM
MIT Kerberos 5 (krb5) through 1.22.2 contains a NULL pointer dereference in make_cred_list() in rd_cred.c that allows authenticated Kerberos clients to crash services by sending mismatched KRB-CRED arrays. Attackers can send forwarded credentials with more tickets than ticket_info entries through gss_accept_sec_context() to crash GSS-API acceptor services, causing denial of service.
CVE-2025-62409 1 Envoyproxy 1 Envoy 2026-10-09 N/A 7.5 HIGH
Envoy is a cloud-native, open source edge and service proxy. Prior to 1.36.1, 1.35.5, 1.34.9, and 1.33.10, large requests and responses can potentially trigger TCP connection pool crashes due to flow control management in Envoy. It will happen when the connection is closing but upstream data is still coming, resulting in a buffer watermark callback nullptr reference. The vulnerability impacts TCP proxy and HTTP 1 & 2 mixed use cases based on ALPN. This vulnerability is fixed in 1.36.1, 1.35.5, 1.34.9, and 1.33.10.
CVE-2025-61908 1 Icinga 1 Icinga 2026-10-09 N/A 6.5 MEDIUM
Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, when creating an invalid reference, such as a reference to null, dereferencing results in a segmentation fault. This can be used by any API user with access to an API endpoint that allows specifying a filter expression to crash the Icinga 2 daemon. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.
CVE-2025-11017 1 Ogre3d 1 Ogre 2026-10-09 1.7 LOW 3.3 LOW
A vulnerability was detected in OGRECave Ogre up to 14.4.1. The impacted element is the function Ogre::LogManager::stream of the file /ogre/OgreMain/src/OgreLogManager.cpp. Performing manipulation of the argument mDefaultLog results in null pointer dereference. The attack must be initiated from a local position. The exploit is now public and may be used.

CVE-2022-1620 3 Apple, Fedoraproject, Vim 3 Macos, Fedora, Vim 2026-10-08 5.0 MEDIUM 7.5 HIGH
NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 in GitHub repository vim/vim prior to 8.2.4901. NULL Pointer Dereference in function vim_regexec_string at regexp.c:2729 allows attackers to cause a denial of service (application crash) via a crafted input.
CVE-2021-3449 12 Checkpoint, Debian, Fedoraproject and 9 more 167 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 164 more 2026-10-08 4.3 MEDIUM 5.9 MEDIUM
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
