Race condition in ip_vs_conn_flush in Linux 2.6 before 2.6.13 and 2.4 before 2.4.32-pre2, when running on SMP systems, allows local users to cause a denial of service (null dereference) by causing a connection timer to expire while the connection table is being flushed before the appropriate lock is acquired.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 7.5 High
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2002-1912 1 Skystream 1 Emr5000 2026-04-16 7.5 High
SkyStream EMR5000 1.16 through 1.18 does not drop packets or disable the Ethernet interface when the buffers are full, which allows remote attackers to cause a denial of service (null pointer exception and kernel panic) via a large number of packets.
CVE-2005-0772 1 Veritas 1 Backup Exec 2026-04-16 7.5 High
VERITAS Backup Exec 9.0 through 10.0 for Windows Servers, and 9.0.4019 through 9.1.307 for Netware, allows remote attackers to cause a denial of service (Remote Agent crash) via (1) a crafted packet in NDMLSRVR.DLL or (2) a request packet with an invalid (non-0) "Error Status" value, which triggers a null dereference.
CVE-2006-2661 4 Canonical, Debian, Freetype and 1 more 4 Ubuntu Linux, Debian Linux, Freetype and 1 more 2026-04-16 N/A
ftutil.c in Freetype before 2.2 allows remote attackers to cause a denial of service (crash) via a crafted font file that triggers a null dereference.
CVE-1999-0052 3 Bsdi, Freebsd, Openbsd 3 Bsd Os, Freebsd, Openbsd 2026-04-16 7.5 High
IP fragmentation denial of service in FreeBSD allows a remote attacker to cause a crash.
CVE-2002-0401 3 Debian, Ethereal, Redhat 4 Debian Linux, Ethereal, Linux and 1 more 2026-04-16 7.5 High
SMB dissector in Ethereal 0.9.3 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via malformed packets that cause Ethereal to dereference a NULL pointer.
CVE-2005-2459 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-04-16 N/A
The huft_build function in inflate.c in the zlib routines in the Linux kernel before 2.6.12.5 returns the wrong value, which allows remote attackers to cause a denial of service (kernel crash) via a certain compressed file that leads to a null pointer dereference, a different vulnerability than CVE-2005-2458.
CVE-2026-21243 1 Microsoft 8 Windows Server 2019, Windows Server 2019 (server Core Installation), Windows Server 2022 and 5 more 2026-04-15 7.5 High
Null pointer dereference in Windows LDAP - Lightweight Directory Access Protocol allows an unauthorized attacker to deny service over a network.
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-2026-40227 2 Systemd, Systemd Project 2 Systemd, Systemd 2026-04-15 6.2 Medium
In systemd 260 before 261, a local unprivileged user can trigger an assert via an IPC API call with an array or map that has a null element.
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-2024-10037 2026-04-15 4.4 Medium
A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability. The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
