CVE-2026-16829 1 Ibm 2 Aix, Vios 2026-10-26 N/A 5.3 MEDIUM
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to a NULL pointer dereference.
CVE-2026-1288 1 Autodesk 1 Revit 2026-10-26 N/A 5.5 MEDIUM
A maliciously crafted RFA file, when converted to FormIt via “Convert RFA to FormIt” in Autodesk Revit, can force a NULL Pointer Dereference vulnerability. Successful exploitation may cause the application to crash, leading to a denial-of-service condition.
CVE-2026-55204 1 Haproxy 1 Haproxy 2026-10-26 N/A 7.5 HIGH
HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpack_dht_insert() within src/hpack-tbl.c that fails to validate the return value of hpack_dht_defrag() when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memory pressure to dereference a NULL pointer and crash HAProxy worker processes, causing denial of service.
CVE-2026-63380 2026-10-26 N/A N/A
Libevent is an event notification library. Prior to 2.2.2-alpha, libevent can dereference invalid list pointers in ws.c when evws_new_session enters its error path after evhttp_start_ws_ succeeds but bufferevent_enable_locking_ fails. evws_connection_free sees a non-null http_server and unconditionally calls TAILQ_REMOVE even though the session was never inserted into http_server->ws_sessions. A local caller able to induce this allocation or locking failure can crash the process. This issue is fixed in version 2.2.2-alpha.
CVE-2026-17165 1 Ibm 2 Aix, Vios 2026-10-26 N/A 7.5 HIGH
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to a NULL pointer dereference.
CVE-2026-16846 1 Ibm 2 Aix, Vios 2026-10-26 N/A 6.5 MEDIUM
IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to a null pointer dereference.
CVE-2026-68901 2026-10-26 N/A 6.5 MEDIUM
Wekan is open source kanban built with Meteor. Prior to 10.38, the /api/boards/:boardId/export, /api/boards/:boardId/attachments/:attachmentId/export, /api/boards/:boardId/export/csv, and /api/boards/:boardId/exportExcel handlers in models/export.js and models/exportExcel.js looked up a user from the attacker-controlled authToken query parameter and immediately called user._id.toString() without checking whether ReactiveCache.getUser() returned undefined. A request for a private board with an unknown token therefore threw a TypeError from an asynchronous route, producing an unhandled rejection that could terminate the Wekan process and deny service to all users. Version 10.38 adds a 401 guard after every export token lookup and wraps export handlers with safeRoute() so unexpected exceptions become controlled responses. This issue is fixed in version 10.38.
CVE-2025-60477 2026-10-26 N/A 5.0 MEDIUM
A NULL pointer dereference in the gf_filter_pid_resolve_file_template_ex function (/filter_core/filter_pid.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted file.
CVE-2026-33601 1 Powerdns 1 Recursor 2026-10-26 N/A 4.4 MEDIUM
If you use the zoneToCache function with a malicious authoritative server, an attacker can send a zone that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service.
CVE-2026-33262 1 Powerdns 1 Recursor 2026-10-26 N/A 5.9 MEDIUM
An attacker can send replies that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service. Cookies are disabled by default.
CVE-2026-6526 1 Wireshark 1 Wireshark 2026-10-26 N/A 5.5 MEDIUM
RTSP protocol dissector crash in Wireshark 4.6.0 to 4.6.4
CVE-2026-34350 1 Microsoft 1 Windows Server 2025 2026-10-26 N/A 6.5 MEDIUM
Null pointer dereference in Windows Storport Miniport Driver allows an unauthorized attacker to deny service over a network.
CVE-2026-57434 1 Nokogiri 1 Nokogiri 2026-10-25 N/A 7.5 HIGH
Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri contains a bug when calling certain methods on allocated-but-uninitialized native wrapper classes that inherit from Nokogiri::XML::Node. This caused a NULL pointer dereference that could crash the process. This vulnerability is fixed in 1.19.4.
CVE-2026-12329 1 Mozilla 2 Firefox, Thunderbird 2026-10-25 N/A 5.3 MEDIUM
Memory safety bug fixed in Thunderbird ESR 140.12. This vulnerability was fixed in Firefox ESR 140.12 and Thunderbird 140.12.
CVE-2026-29169 1 Apache 1 Http Server 2026-10-25 N/A 7.5 HIGH
A NULL pointer dereference in mod_dav_lock in Apache HTTP Server 2.4.66 and earlier may allow an attacker to crash the server with a malicious request.mod_dav_lock is not used internally by mod_dav or mod_dav_fs. The only known use-case for mod_dav_lock was mod_dav_svn from Apache Subversion earlier than version 1.2.0. Users are recommended to upgrade to version 2.4.66, which fixes this issue, or remove mod_dav_lock.
CVE-2026-10852 1 Ibm 1 I 2026-10-25 N/A 5.9 MEDIUM
IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to denial of service in the WebSphere WebServer Plug-in component when an attacker can pass crafted requests to the web server.
CVE-2026-0156 1 Google 1 Android 2026-10-25 N/A 7.5 HIGH
In checkSsrcCollisionOnRcv of RtpSession.cpp, there is a possible memory safety issue due to a missing null check. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-8359 2026-10-25 N/A 7.5 HIGH
When processing a request with a URL path starting with /status or /sysinfo, WOSHttpStatusModule.dll is to be loaded to handle such URL patterns. The WOSBin_LoadHttpModule function in the dll would be called to set up a "module" object for that module. However, WOSHttpStatusModule.dll is not present in the installation. As a result, a function pointer to WOSBin_LoadHttpModule (which would have been in the export table in WOSHttpStatusModule.dll) is set to NULL, resulting in calling a function at address 0.
CVE-2026-9716 1 Schneider-electric 2 Powerlogic P7, Powerlogic P7 Firmware 2026-10-25 N/A 7.5 HIGH
CWE-476 NULL Pointer Dereference vulnerability exists that could cause a denial-of-service condition, rendering the device’s HMI and configuration functionality unavailable when malformed requests are received over exposed network interfaces.
CVE-2026-57875 2026-10-25 N/A 7.5 HIGH
An unauthenticated NULL pointer dereference vulnerability exists in the HTTP request parsing logic of multiple CGI components in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by improper validation of required HTTP request metadata before it is used by the affected components. A remote attacker may exploit this vulnerability by sending a specially crafted HTTP request, causing the affected process to crash and resulting in a denial of service.
