CVE-2024-20266 1 Cisco 1 Ios Xr Software 2026-04-15 5.3 Medium
A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition. This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a crash of the dhcpd process. While the dhcpd process is restarting, which may take approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period and rely on the DHCPv4 server of the affected device. Notes: Only the dhcpd process crashes and eventually restarts automatically. The router does not reload. This vulnerability only applies to DHCPv4. DHCP version 6 (DHCPv6) is not affected.
CVE-2025-23330 1 Nvidia 1 Display Driver 2026-04-15 5.5 Medium
NVIDIA Display Driver for Linux contains a vulnerability where an attacker might be able to trigger a null pointer dereference. A successful exploit of this vulnerability might lead to denial of service.
CVE-2024-43167 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-04-15 2.8 Low
DISPUTE NOTE: this issue does not pose a security risk as it (according to analysis by the original software developer, NLnet Labs) falls within the expected functionality and security controls of the application. Red Hat has made a claim that there is a security risk within Red Hat products. NLnet Labs has no further information about the claim, and suggests that affected Red Hat customers refer to available Red Hat documentation or support channels. ORIGINAL DESCRIPTION: A NULL pointer dereference flaw was found in the ub_ctx_set_fwd function in Unbound. This issue could allow an attacker who can invoke specific sequences of API calls to cause a segmentation fault. When certain API functions such as ub_ctx_set_fwd and ub_ctx_resolvconf are called in a particular order, the program attempts to read from a NULL pointer, leading to a crash. This issue can result in a denial of service by causing the application to terminate unexpectedly.
CVE-2024-56430 2026-04-15 2.9 Low
OpenFHE through 1.2.3 has a NULL pointer dereference in BinFHEContext::EvalFloor in lib/binfhe-base-scheme.cpp.
CVE-2023-51391 1 Silabs 1 Gecko Software Development Kit 2026-04-15 7.5 High

The web server of the affected devices do not properly handle certain requests, causing a timeout in the watchdog, which could lead to the clean up of pointers. This could allow a remote attacker to cause a denial of service condition in the system.
CVE-2023-30755 2026-04-15 4.4 Medium

The web server of the affected devices do not properly handle the shutdown or reboot request, which could lead to the clean up of certain resources. This could allow a remote attacker with elevated privileges to cause a denial of service condition in the system.
CVE-2024-24443 2026-04-15 6.5 Medium
An uninitialized pointer dereference in the ngap_handle_pdu_session_resource_setup_response routine of OpenAirInterface CN5G AMF (oai-cn5g-amf) up to v2.0.0 allows attackers to cause a Denial of Service (DoS) via a crafted PDU Session Resource Setup Response.
CVE-2024-47586 1 Sap 1 Netweaver Abap Application Server 2026-04-15 5.3 Medium
SAP NetWeaver Application Server for ABAP and ABAP Platform allows an unauthenticated attacker to send a maliciously crafted http request which could cause a null pointer dereference in the kernel. This dereference will result in the system crashing and rebooting, causing the system to be temporarily unavailable. There is no impact on Confidentiality or Integrity.
CVE-2024-48294 1 Wondershare Pdf Reader 1 Wondershare Pdf Reader 2026-04-15 5.5 Medium
A NULL pointer dereference in the component libPdfCore.dll of Wondershare PDF Reader v1.0.9.2544 allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.
CVE-2024-54130 1 Nasajpl 1 Iondtn 2026-04-15 N/A
The NASA’s Interplanetary Overlay Network (ION) is an implementation of Delay/Disruption Tolerant Networking (DTN). A segmentation fault occurs with ION-DTN BPv7 software version 4.1.3 when a bundle with a Destination Endpoint ID (EID) set to dtn:none is received. This causes the node to become unresponsive to incoming bundles, leading to a Denial of Service (DoS) condition. This vulnerability is fixed in 4.1.3s.
CVE-2023-45935 2026-04-15 4.2 Medium
Qt 6 through 6.6 was discovered to contain a NULL pointer dereference via the function QXcbConnection::initializeAllAtoms(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.
CVE-2024-24194 1 Robdns 1 Robdns 2026-04-15 7.5 High
robdns commit d76d2e6 was discovered to contain a NULL pointer dereference via the item->tokens component at /src/conf-parse.c.

CVE-2025-6398 1 Asus 1 Ai Suite 2026-04-15 N/A
A null pointer dereference vulnerability exists in the IOMap64.sys driver of ASUS AI Suite 3. The vulnerability can be triggered by a specially crafted input, which may lead to a system crash (BSOD). Refer to the ' Security Update for for AI Suite 3 ' section on the ASUS Security Advisory for more information.
CVE-2023-46046 2026-04-15 5.5 Medium
An issue in MiniZinc before 2.8.0 allows a NULL pointer dereference via ti_expr in a crafted .mzn file. NOTE: this is disputed because there is no common libminizinc use case in which an unattended process is supposed to run forever to process a series of atttacker-controlled .mzn files.
CVE-2025-40255 1 Linux 1 Linux Kernel 2026-04-15 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: core: prevent NULL deref in generic_hwtstamp_ioctl_lower() The ethtool tsconfig Netlink path can trigger a null pointer dereference. A call chain such as: tsconfig_prepare_data() -> dev_get_hwtstamp_phylib() -> vlan_hwtstamp_get() -> generic_hwtstamp_get_lower() -> generic_hwtstamp_ioctl_lower() results in generic_hwtstamp_ioctl_lower() being called with kernel_cfg->ifr as NULL. The generic_hwtstamp_ioctl_lower() function does not expect a NULL ifr and dereferences it, leading to a system crash. Fix this by adding a NULL check for kernel_cfg->ifr in generic_hwtstamp_ioctl_lower(). If ifr is NULL, return -EINVAL.
CVE-2023-46049 2026-04-15 5.3 Medium
LLVM 15.0.0 has a NULL pointer dereference in the parseOneMetadata() function via a crafted pdflatex.fmt file (or perhaps a crafted .o file) to llvm-lto. NOTE: this is disputed because the relationship between pdflatex.fmt and any LLVM language front end is not explained, and because a crash of the llvm-lto application should be categorized as a usability problem.
CVE-2024-45969 1 Mz-automation 1 Libiec61850 2026-04-15 7.5 High
NULL pointer dereference in the MMS Client in MZ Automation LibIEC1850 before commit 7afa40390b26ad1f4cf93deaa0052fe7e357ef33 allows a malicious server to Cause a Denial-of-Service via the MMS InitiationResponse message.
