| CVE-2004-0119 | 1 Microsoft | 3 Windows 2000, Windows Server 2003, Windows Xp | 2026-04-16 | 7.5 High |
| The Negotiate Security Software Provider (SSP) interface in Windows 2000, Windows XP, and Windows Server 2003, allows remote attackers to cause a denial of service (crash from null dereference) or execute arbitrary code via a crafted SPNEGO NegTokenInit request during authentication protocol selection. | ||||

| 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-2025-53603 | 1 Alinto | 1 Sogo | 2026-04-15 | 7.5 High |
| In Alinto SOPE SOGo 2.0.2 through 5.12.2, sope-core/NGExtensions/NGHashMap.m allows a NULL pointer dereference and SOGo crash via a request in which a parameter in the query string is a duplicate of a parameter in the POST body. | ||||
| 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-2024-41884 | 2026-04-15 | N/A | ||
| Team ENVY, a Security Research TEAM has found a flaw that allows for a remote code execution on the NVR. If an attacker does not enter any value for a specific URL parameter, NULL pointer references will occur and the NVR will reboot. The manufacturer has released patch firmware for the flaw, please refer to the manufacturer's report for details and workarounds. | ||||

| 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-2024-11499 | 2026-04-15 | 4.9 Medium | ||
| A vulnerability exists in RTU500 IEC 60870-4-104 controlled station functionality, that allows an authenticated and authorized attacker to perform a CMU restart. The vulnerability can be triggered if certificates are updated while in use on active connections. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability. | ||||
| 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. | ||||
