CVE-2026-3776 4 Apple, Foxit, Foxitsoftware and 1 more 6 Macos, Pdf Editor, Pdf Reader and 3 more 2026-04-15 5.5 Medium
The application does not validate the presence of required appearance (AP) data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service.
CVE-2026-40227 2 Systemd, Systemd Project 2 Systemd, Systemd 2026-04-15 6.2 Medium
In systemd 260 before 261, a local unprivileged user can trigger an assert via an IPC API call with an array or map that has a null element.
CVE-2024-39130 1 Wangf1978 1 Dumpts 2026-04-15 7.5 High
A NULL Pointer Dereference discovered in DumpTS v0.1.0-nightly allows attackers to cause a denial of service via the function DumpOneStream() at /src/DumpStream.cpp.
CVE-2024-3184 1 Embedthis 1 Goahead 2026-04-15 5.9 Medium
Multiple CWE-476 NULL Pointer Dereference vulnerabilities were found in GoAhead Web Server up to version 6.0.0 when compiled with the ME_GOAHEAD_REPLACE_MALLOC flag. Without a memory notifier for allocation failures, remote attackers can exploit these vulnerabilities by sending malicious requests, leading to a crash and Denial of Service (DoS).
CVE-2025-40779 1 Isc 1 Kea 2026-04-15 7.5 High
If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem. This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0.
CVE-2025-6496 1 Htacg 1 Tidy 2026-04-15 3.3 Low
A vulnerability was found in HTACG tidy-html5 5.8.0. It has been declared as problematic. This vulnerability affects the function InsertNodeAsParent of the file src/parser.c. The manipulation leads to null pointer dereference. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used.
CVE-2025-32818 2026-04-15 7.5 High
A Null Pointer Dereference vulnerability in the SonicOS SSLVPN Virtual office interface allows a remote, unauthenticated attacker to crash the firewall, potentially leading to a Denial-of-Service (DoS) condition.
CVE-2024-37820 1 Pingcap 1 Tidb 2026-04-15 5.4 Medium
A nil pointer dereference in PingCAP TiDB v8.2.0-alpha-216-gfe5858b allows attackers to crash the application via expression.inferCollation.
CVE-2024-24856 2026-04-15 5.3 Medium
The memory allocation function ACPI_ALLOCATE_ZEROED does not guarantee a successful allocation, but the subsequent code directly dereferences the pointer that receives it, which may lead to null pointer dereference. To fix this issue, a null pointer check should be added. If it is null, return exception code AE_NO_MEMORY.
CVE-2025-20262 1 Cisco 4 Nexus, Nexus 3000, Nexus 9000 and 1 more 2026-04-15 5 Medium
A vulnerability in the Protocol Independent Multicast Version 6 (PIM6) feature of Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an authenticated, low-privileged, remote attacker to trigger a crash of the PIM6 process, resulting in a denial of service (DoS) condition. This vulnerability is due to improper processing of PIM6 ephemeral data queries. An attacker could exploit this vulnerability by sending a crafted ephemeral query to an affected device through one of the following methods: NX-API REST, NETCONF, RESTConf, gRPC, or Model Driven Telemetry. A successful exploit could allow the attacker to cause the PIM6 process to crash and restart, causing potential adjacency flaps and resulting in a DoS of the PIM6 and ephemeral query processes.
CVE-2025-61668 1 Plone 1 Volto 2026-04-15 N/A
Volto is a ReactJS-based frontend for the Plone Content Management System. Versions 16.34.0 and below, 17.0.0 through 17.22.1, 18.0.0 through 18.27.1, and 19.0.0-alpha.1 through 19.0.0-alpha.5, an anonymous user could cause the NodeJS server part of Volto to quit with an error when visiting a specific URL. This issue is fixed in versions 16.34.1, 17.22.2, 18.27.2 and 19.0.0-alpha.6.
CVE-2024-10037 2026-04-15 4.4 Medium
A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
CVE-2024-39132 2026-04-15 6.5 Medium
A NULL Pointer Dereference vulnerability in DumpTS v0.1.0-nightly allows attackers to cause a denial of service via the function VerifyCommandLine() at /src/DumpTS.cpp.
CVE-2023-37039 2026-04-15 6.5 Medium
A Null pointer dereference vulnerability in the Mobile Management Entity (MME) in Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) allow network-adjacent attackers to crash the MME via an S1AP `Initial UE Message` packet missing an expected `RRC Establishment Clause` field.
CVE-2025-15156 1 Omec-project 1 Upf 2026-04-15 4.3 Medium
A flaw has been found in omec-project UPF up to 2.1.3-dev. This affects the function handleSessionEstablishmentRequest of the file /pfcpiface/pfcpiface/messages_session.go of the component PFCP Session Establishment Request Handler. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2023-37035 2026-04-15 6.5 Medium
A Null pointer dereference vulnerability in the Mobile Management Entity (MME) in Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) allows network-adjacent attackers to crash the MME via an S1AP `S1Setup Request` packet missing an expected `Global eNB ID` field.
CVE-2025-8865 1 Yugabyte 1 Yugabytedb 2026-04-15 2.0 Low
The YugabyteDB tablet server contains a flaw in its YCQL query handling that can trigger a null pointer dereference when processing certain malformed inputs. An authenticated attacker could exploit this issue to crash the YCQL tablet server, resulting in a denial of service.
CVE-2025-70954 1 Ton-blockchain 1 Ton 2026-04-15 7.5 High
A Null Pointer Dereference vulnerability exists in the TON Virtual Machine (TVM) within the TON Blockchain before v2025.06. The issue is located in the execution logic of the INMSGPARAM instruction, where the program fails to validate if a specific pointer is null before accessing it. By sending a malicious transaction or smart contract, an attacker can trigger this null pointer dereference, causing the validator node process to crash (segmentation fault). This results in a Denial of Service (DoS) affecting the availability of the entire blockchain network.
CVE-2024-20446 1 Cisco 1 Nx-os 2026-04-15 8.6 High
A vulnerability in the DHCPv6 relay agent of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific fields in a DHCPv6 RELAY-REPLY message. An attacker could exploit this vulnerability by sending a crafted DHCPv6 packet to any IPv6 address that is configured on an affected device. A successful exploit could allow the attacker to cause the dhcp_snoop process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition.
