CVE-2025-8090 1 Blackberry 2 Qnx Os For Safety, Qnx Software Development Platform 2026-04-15 6.2 Medium
Null pointer dereference in the MsgRegisterEvent() system call could allow an attacker with local access and code execution abilities to crash the QNX Neutrino kernel.
CVE-2024-0079 1 Nvidia 1 Gpu Display Driver 2026-04-15 6.5 Medium
NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a user in a guest VM can cause a NULL-pointer dereference in the host. A successful exploit of this vulnerability may lead to denial of service.
CVE-2023-45924 1 Opengl 1 Libglvnd-bb06db5a 2026-04-15 9.8 Critical
libglxproto.c in OpenGL libglvnd bb06db5a was discovered to contain a segmentation violation via the function glXGetDrawableScreen(). NOTE: this is disputed because there are no common situations in which users require uninterrupted operation with an attacker-controller server.
CVE-2023-45925 1 Midnight Commander 1 Midnight Commander 2026-04-15 N/A
GNU Midnight Commander 4.8.29-146-g299d9a2fb was discovered to contain a NULL pointer dereference via the function x_error_handler() at tty/x11conn.c. NOTE: this is disputed because it should be categorized as a usability problem (an X operation silently fails).
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.

This could allow a remote attacker with elevated privileges to cause a denial of service condition in the system.
CVE-2023-50432 2026-04-15 5.3 Medium
simple-dhcp-server through ec976d2 allows remote attackers to cause a denial of service (daemon crash) by sending a DHCP packet without any option fields, which causes free_packet in dhcp_packet.c to dereference a NULL pointer.
CVE-2023-30756 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.

The web server of the affected devices do not properly handle certain errors when using the Expect HTTP request header, resulting in NULL dereference. This could allow a remote attacker with no privileges to cause a denial of service condition in the system.
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-2025-45525 2026-04-15 2.9 Low
A NULL pointer dereference vulnerability has been identified in the JavaScript library microlight version 0.0.7, a lightweight syntax highlighting library. When processing elements with non-standard CSS color values, the library fails to validate the result of a regular expression match before accessing its properties, leading to an uncaught TypeError and potential application crash. NOTE: this is disputed by multiple parties because there is no common scenario in which an adversary can insert those non-standard values.
CVE-2025-24031 2026-04-15 3.3 Low
PAM-PKCS#11 is a Linux-PAM login module that allows a X.509 certificate based user login. In versions 0.6.12 and prior, the pam_pkcs11 module segfaults when a user presses ctrl-c/ctrl-d when they are asked for a PIN. When a user enters no PIN at all, `pam_get_pwd` will never initialize the password buffer pointer and as such `cleanse` will try to dereference an uninitialized pointer. On my system this pointer happens to have the value 3 most of the time when running sudo and as such it will segfault. The most likely impact to a system affected by this issue is an availability impact due to a daemon that uses PAM crashing. As of time of publication, a patch for the issue is unavailable.
CVE-2025-30195 1 Powerdns 1 Recursor 2026-04-15 7.5 High
An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service. The remedy is: upgrade to the patched 5.2.1 version. We would like to thank Volodymyr Ilyin for bringing this issue to our attention.
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-2024-1241 2026-04-15 5.5 Medium
Watchdog Antivirus v1.6.415 is vulnerable to a Denial of Service vulnerability by triggering the 0x80002014 IOCTL code of the wsdk-driver.sys driver.
CVE-2024-0075 1 Nvidia 1 Gpu Display Driver 2026-04-15 6.1 Medium
NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability where a user may cause a NULL-pointer dereference by accessing passed parameters the validity of which has not been checked. A successful exploit of this vulnerability may lead to denial of service and limited information disclosure.
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.
