cupsd in CUPS 1.3.9 and earlier allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. NOTE: this issue can be triggered remotely by leveraging CVE-2008-5184.
CVE-2009-1181 5 Apple, Foolabs, Glyphandcog and 2 more 5 Cups, Xpdf, Xpdfreader and 2 more 2026-04-23 N/A
The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (crash) via a crafted PDF file that triggers a NULL pointer dereference.
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."

The d_delete function in fs/ecryptfs/inode.c in eCryptfs in the Linux kernel 2.6.31 allows local users to cause a denial of service (kernel OOPS) and possibly execute arbitrary code via unspecified vectors that cause a "negative dentry" and trigger a NULL pointer dereference, as demonstrated via a Mutt temporary directory in an eCryptfs mount.

The XMPP protocol plugin in libpurple in Pidgin before 2.6.2 does not properly handle an error IQ stanza during an attempted fetch of a custom smiley, which allows remote attackers to cause a denial of service (application crash) via XHTML-IM content with cid: images.
CVE-2009-1574 2 Ipsec-tools, Redhat 2 Ipsec-tools, Enterprise Linux 2026-04-23 N/A
racoon/isakmp_frag.c in ipsec-tools before 0.7.2 allows remote attackers to cause a denial of service (crash) via crafted fragmented packets without a payload, which triggers a NULL pointer dereference.

The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.
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-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-2026-6778 1 Mozilla 2 Firefox, Thunderbird 2026-04-22 5.3 Medium
Invalid pointer in the Audio/Video: Playback component. This vulnerability was fixed in Firefox 150 and Thunderbird 150.
