CVE-2023-46051 2026-04-15 3.3 Low
TeX Live 944e257 allows a NULL pointer dereference in texk/web2c/pdftexdir/tounicode.c. NOTE: this is disputed because it should be categorized as a usability problem.
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.

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-2023-28827 2026-04-15 5.9 Medium
A vulnerability has been identified in SIMATIC CP 1242-7 V2 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 DNP3 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 IEC (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-7 LTE (All versions < V3.5.20), SIMATIC CP 1243-8 IRC (6GK7243-8RX30-0XE0) (All versions < V3.5.20), SIMATIC HMI Comfort Panels (incl. SIPLUS variants) (All versions), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMATIC WinCC Runtime Advanced (All versions), SIPLUS TIM 1531 IRC (6AG1543-1MX00-7XE0) (All versions < V2.4.8), TIM 1531 IRC (6GK7543-1MX00-0XE0) (All versions < V2.4.8). 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-2025-23300 1 Nvidia 1 Display Driver 2026-04-15 5.5 Medium
NVIDIA Display Driver for Linux contains a vulnerability in the kernel driver, where a user could cause a null pointer dereference by allocating a specific memory resource. A successful exploit of this vulnerability might lead to denial of service.
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-2025-23332 2 Linux, Nvidia 10 Linux, Display Driver, Driver and 7 more 2026-04-15 5 Medium
NVIDIA Display Driver for Linux contains a vulnerability in a kernel module, where an attacker might be able to trigger a null pointer deference. A successful exploit of this vulnerability might lead to denial of service.
CVE-2025-41691 1 Codesys 1 Control 2026-04-15 7.5 High
An unauthenticated remote attacker may trigger a NULL pointer dereference in the affected CODESYS Control runtime systems by sending specially crafted communication requests, potentially leading to a denial-of-service (DoS) condition.
CVE-2025-25471 1 Ffmpeg 1 Ffmpeg 2026-04-15 4.3 Medium

CVE-2025-25473 1 Ffmpeg 1 Ffmpeg 2026-04-15 5.3 Medium
FFmpeg git master before commit c08d30 was discovered to contain a memory leak in the avformat_free_context function in libavutil/mem.c.
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-2026-32696 2 Emqx, Nanomq 2 Nanomq, Nanomq 2026-04-14 3.1 Low
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. In NanoMQ version 0.24.6, after enabling auth.http_auth (HTTP authentication), when a client connects to the broker using MQTT CONNECT without providing username/password, and the configuration params uses the placeholders %u / %P (e.g., username="%u", password="%P"), the HTTP request construction phase enters auth_http.c:set_data(). This results in calling strlen() on a NULL pointer, causing a SIGSEGV crash. This crash can be triggered remotely, resulting in a denial of service. This issue has been patched in version 0.24.7.
CVE-2026-25168 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-04-14 6.2 Medium
