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-2025-14309 1 Ravynsoft 1 Ravynos 2026-04-15 7.5 High
NULL Pointer Dereference vulnerability in ravynsoft ravynos.This issue affects ravynos: through 0.5.2.
CVE-2025-14841 1 Offis 1 Dcmtk 2026-04-15 3.3 Low
A flaw has been found in OFFIS DCMTK up to 3.6.9. The impacted element is the function DcmQueryRetrieveIndexDatabaseHandle::startFindRequest/DcmQueryRetrieveIndexDatabaseHandle::startMoveRequest in the library dcmqrdb/libsrc/dcmqrdbi.cc of the component dcmqrscp. This manipulation causes null pointer dereference. The attack requires local access. Upgrading to version 3.7.0 is sufficient to resolve this issue. Patch name: ffb1a4a37d2c876e3feeb31df4930f2aed7fa030. You should upgrade the affected component.
CVE-2023-51391 1 Silabs 1 Gecko Software Development Kit 2026-04-15 7.5 High
A bug in Micrium OS Network HTTP Server permits an invalid pointer dereference during header processing - potentially allowing a device crash and Denial of Service.
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-2023-46051 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.

Tex Live 944e257 has a NULL pointer dereference in texk/web2c/pdftexdir/writet1.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.
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-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-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-2025-9548 2 Lenovo, Microsoft 2 Power Management Driver, Windows 2026-04-15 5.5 Medium
A potential null pointer dereference vulnerability was reported in the Lenovo Power Management Driver that could allow a local authenticated user to cause a Windows blue screen error.
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-2025-40255 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.
