CVE-2009-0949 6 Apple, Canonical, Debian and 3 more 8 Cups, Mac Os X, Mac Os X Server and 5 more 2026-04-23 7.5 High
The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.

cmsxform.c in LittleCMS (aka lcms or liblcms) 1.18, as used in OpenJDK and other products, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted image that triggers execution of incorrect code for "transformations of monochrome profiles."
CVE-2009-0845 2 Mit, Redhat 3 Kerberos, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via invalid ContextFlags data in the reqFlags field in a negTokenInit token.
CVE-2009-2516 1 Microsoft 5 Windows 2000, Windows Server 2003, Windows Server 2008 and 2 more 2026-04-23 7.1 High
The kernel in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold and SP1, and Server 2008 Gold does not properly validate data sent from user mode, which allows local users to gain privileges via a crafted PE .exe file that triggers a NULL pointer dereference during chain traversal, aka "Windows Kernel NULL Pointer Dereference Vulnerability."
CVE-2009-2692 4 Debian, Linux, Redhat and 1 more 11 Debian Linux, Linux Kernel, Enterprise Linux and 8 more 2026-04-23 7.8 High
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.
CVE-2009-2698 6 Canonical, Fedoraproject, Linux and 3 more 14 Ubuntu Linux, Fedora, Linux Kernel and 11 more 2026-04-23 7.8 High

Skulltag before 0.97d2-RC6 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by sending a "command 29" packet when the player is not in the game.
CVE-2006-4343 4 Canonical, Debian, Openssl and 1 more 5 Ubuntu Linux, Debian Linux, Openssl and 2 more 2026-04-23 N/A
The get_server_hello function in the SSLv2 client code in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows remote servers to cause a denial of service (client crash) via unknown vectors that trigger a null pointer dereference.
CVE-2007-5938 2 Intel, Redhat 3 Pro Wireless 3945abg, Wireless Wifi Link 4965agn, Enterprise Linux 2026-04-23 N/A
The iwl_set_rate function in compatible/iwl3945-base.c in iwlwifi 1.1.21 and earlier dereferences an iwl_get_hw_mode return value without checking for NULL, which might allow remote attackers to cause a denial of service (kernel panic) via unspecified vectors during module initialization.
CVE-2007-4565 2 Fetchmail, Redhat 2 Fetchmail, Enterprise Linux 2026-04-23 N/A
sink.c in fetchmail before 6.3.9 allows context-dependent attackers to cause a denial of service (NULL dereference and application crash) by refusing certain warning messages that are sent over SMTP.
CVE-2007-1420 3 Mysql, Oracle, Redhat 3 Mysql, Mysql, Enterprise Linux 2026-04-23 N/A
MySQL 5.x before 5.0.36 allows local users to cause a denial of service (database crash) by performing information_schema table subselects and using ORDER BY to sort a single-row result, which prevents certain structure elements from being initialized and triggers a NULL dereference in the filesort function.
CVE-2007-1327 1 Silc 1 Silc-server 2026-04-23 N/A
The SILC_SERVER_CMD_FUNC function in apps/silcd/command.c in silc-server 1.0.2 allows remote attackers to cause a denial of service (NULL dereference and daemon crash) via a request without a cipher algorithm and an invalid HMAC algorithm.
CVE-2025-69651 1 Gnu 1 Binutils 2026-04-22 5.5 Medium
GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an invalid pointer free when processing a crafted ELF binary with malformed relocation or symbol data. If dump_relocations returns early due to parsing errors, the internal all_relocations array may remain partially uninitialized. Later, process_got_section_contents() may attempt to free an invalid r_symbol pointer, triggering memory corruption checks in glibc and causing the program to terminate with SIGABRT. No evidence of further memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version.
CVE-2026-21525 1 Microsoft 30 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 27 more 2026-04-22 6.2 Medium
Null pointer dereference in Windows Remote Access Connection Manager allows an unauthorized attacker to deny service locally.
CVE-2025-71233 1 Linux 1 Linux Kernel 2026-04-20 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Avoid creating sub-groups asynchronously The asynchronous creation of sub-groups by a delayed work could lead to a NULL pointer dereference when the driver directory is removed before the work completes. The crash can be easily reproduced with the following commands: # cd /sys/kernel/config/pci_ep/functions/pci_epf_test # for i in {1..20}; do mkdir test && rmdir test; done BUG: kernel NULL pointer dereference, address: 0000000000000088 ... Call Trace: configfs_register_group+0x3d/0x190 pci_epf_cfs_work+0x41/0x110 process_one_work+0x18f/0x350 worker_thread+0x25a/0x3a0 Fix this issue by using configfs_add_default_group() API which does not have the deadlock problem as configfs_register_group() and does not require the delayed work handler. [mani: slightly reworded the description and added stable list]
CVE-2025-8033 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2026-04-20 6.5 Medium
The JavaScript engine did not handle closed generators correctly and it was possible to resume them leading to a nullptr deref. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1.
CVE-2025-38562 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-04-20 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference error in generate_encryptionkey If client send two session setups with krb5 authenticate to ksmbd, null pointer dereference error in generate_encryptionkey could happen. sess->Preauth_HashValue is set to NULL if session is valid. So this patch skip generate encryption key if session is valid.
