CVE-2024-47809 1 Linux 1 Linux Kernel 2026-07-14 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: dlm: fix possible lkb_resource null dereference This patch fixes a possible null pointer dereference when this function is called from request_lock() as lkb->lkb_resource is not assigned yet, only after validate_lock_args() by calling attach_lkb(). Another issue is that a resource name could be a non printable bytearray and we cannot assume to be ASCII coded. The log functionality is probably never being hit when DLM is used in normal way and no debug logging is enabled. The null pointer dereference can only occur on a new created lkb that does not have the resource assigned yet, it probably never hits the null pointer dereference but we should be sure that other changes might not change this behaviour and we actually can hit the mentioned null pointer dereference. In this patch we just drop the printout of the resource name, the lkb id is enough to make a possible connection to a resource name if this exists.
CVE-2024-42079 1 Linux 1 Linux Kernel 2026-07-14 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix NULL pointer dereference in gfs2_log_flush In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush lock to provide exclusion against gfs2_log_flush(). In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before dereferencing it. Otherwise, we could run into a NULL pointer dereference when outstanding glock work races with an unmount (glock_work_func -> run_queue -> do_xmote -> inode_go_sync -> gfs2_log_flush).
CVE-2026-6845 2 Gnu, Redhat 4 Binutils, Enterprise Linux, Hardened Images and 1 more 2026-07-13 N/A 5.0 MEDIUM
A flaw was found in binutils, specifically within the `readelf` utility. This vulnerability allows a local attacker to cause a Denial of Service (DoS) by tricking a user into processing a specially crafted Executable and Linkable Format (ELF) file. The exploitation of this flaw can lead to the system becoming unresponsive due to excessive resource consumption or a program crash.
CVE-2026-44512 1 Linuxfoundation 1 Onnx 2026-07-13 N/A 5.5 MEDIUM
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. From 1.9.0 before 1.22.0, onnx.version_converter.convert_version() can dereference a null pointer in Upsample_6_7::adapt_upsample_6_7() in onnx/version_converter/adapters/upsample_6_7.h when processing an untrusted model with an Upsample node that has zero inputs, causing an unrecoverable denial of service. This issue is fixed in version 1.22.0.
CVE-2026-58250 1 Linuxfoundation 1 Nats-server 2026-07-13 N/A 7.5 HIGH
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.12.8 and 2.11.17, an unauthenticated peer with network access to a leafnode listener with compression enabled could crash the server during the pre-authentication leafnode handshake by sending repeated leafnode INFO protocol messages before authentication and account setup completed. This issue is fixed in versions 2.12.8 and 2.11.17.
CVE-2026-56288 1 Gnu 1 Patch 2026-07-13 N/A 5.5 MEDIUM
GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing. An attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service. This issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313
CVE-2026-55783 2026-07-10 N/A N/A
NanaZip is the 7-Zip derivative intended for the modern Windows experience. Prior to 6.5.1749.0, NanaZip's seven in-house IInArchive handlers in NanaZip.Codecs unconditionally dereference the caller-supplied Indices array inside Extract when the archive engine signals extract everything by passing Indices as NULL and NumItems as 0xFFFFFFFF. This causes a NULL pointer dereference in the standard Test archive or Extract all code path for WebAssembly, ElectronAsar, Zealfs, Romfs, Ufs, Littlefs, and DotNetSingleFile archives, resulting in a process crash. This issue is fixed in version 6.5.1749.0.
CVE-2026-50810 2026-07-10 N/A 5.5 MEDIUM
A NULL pointer dereference in smooth_parse_stream_index() in src/media_tools/mpd.c in GPAC master HEAD before commit b35c61f104b85fbb16520ac2838d5d2ef70845b5 allows attackers to cause a denial of service
CVE-2026-21901 2026-07-10 N/A 4.4 MEDIUM
A NULL Pointer Dereference vulnerability in the management daemon (mgd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, high-privileged attacker setting or deactivating a specific SSH configuration parameter to create a Denial of Service (DoS). A local high-privileged user configuring or deactivating a specific 'system services ssh' configuration parameter can exploit a null pointer dereference in one of the functions used by SSH. The function attempts to dereference a null pointer when accessing certain configuration data, resulting in an mgd process crash and restart. Continued execution of these configuration commands will create a sustained Denial of Service (DoS) condition. This issue affects: Junos OS: * from 22.3 before 22.3R3-S5; * from 22.4 before 22.4R3-S10; * from 23.2 before 23.2R2-S7; * from 23.4 before 23.4R2-S8. This issue does not affect Junos OS before 22.3R1. Junos OS Evolved: * from 22.3R1-EVO before 23.2R2-S7-EVO; * from 23.4 before 23.4R2-S8-EVO. This issue does not affect Junos OS Evolved before 22.3R1-EVO.
CVE-2026-10852 1 Ibm 1 I 2026-07-09 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-2026-50812 2026-07-09 N/A 5.5 MEDIUM
A NULL pointer dereference in the SQLite Session Extension in SQLite 3.53.1 and SQLite trunk builds before check-in e807d4e3798efd53 allows an attacker who can supply a malformed changeset blob to cause a denial of service. The issue occurs when sqlite3changeset_apply_v3() applies a corrupt changeset and reaches sqlite3_value_type() with a NULL sqlite3_value pointer.
CVE-2026-15171 1 Wireshark 1 Wireshark 2026-07-09 N/A 5.5 MEDIUM
SSH protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service
CVE-2026-15184 2026-07-09 1.7 LOW 3.3 LOW
A vulnerability was found in GNU LibreDWG up to 0.13.4. The impacted element is the function dwg_next_entity of the file src/dwg.c of the component DWG File Handler. Performing a manipulation of the argument next_obj results in null pointer dereference. The attack must be initiated from a local position. The exploit has been made public and could be used. Upgrading to version 0.14 is sufficient to resolve this issue. The patch is named dde45dac3c4d902e4d8fed150a8017b9732019c9. Upgrading the affected component is recommended. Different than CVE-2026-9503.
