| CVE-2026-17251 | 1 Tp-link | 1 Tl-mr6400 V7 | 2026-08-21 | N/A |
| A NULL pointer dereference vulnerability exists in the HTTP request parsing functionality of TL-MR6400 v7. An unauthenticated remote attacker can trigger the vulnerability by sending a specially crafted HTTP request containing a malformed session cookie header. Successful exploitation may cause the HTTP service process to crash, resulting in a denial-of-service condition and temporary loss of management or CGI functionality until service recovery. | ||||
| CVE-2026-47753 | 1 Lxc | 1 Incus | 2026-08-21 | N/A |
| Incus is a system container and virtual machine manager. Prior to version 7.1.0, `(*backend).CreateInstanceFromBackup` in `internal/server/storage/backend.go` contains a nil-pointer dereference that an authenticated user with permission to create instances in any project can trigger remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing denial of service to every project on that cluster member. This is a sibling of `GHSA-fwj8-62r8-8p8m`, `GHSA-r7w7-mmxr-47r9`, and `GHSA-x5r6-jr56-89pv` (all assigned 2026-05-04). Those patches added guards on adjacent fields of the same `backup/config.Config` struct; the `Volume` field on the instance-import path was missed. Version 7.1.0 contains an updated patch. | ||||
| CVE-2026-59949 | 1 Yawkat | 1 Lz4-java | 2026-08-21 | 6.5 Medium |
| yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.1, JNI-backed XXHash implementations fail to validate the byte array object and the off and len arguments in XXHashFactory.nativeInstance().hash32().hash(), XXHashFactory.nativeInstance().hash64().hash(), XXHashFactory.nativeInstance().newStreamingHash32().update(), and XXHashFactory.nativeInstance().newStreamingHash64().update(), allowing null arrays or oversized ranges to reach native code, read outside the Java array, and fatally terminate the JVM. This issue is fixed in version 1.11.1. | ||||
| CVE-2026-50126 | 1 Knmi | 1 Adaguc-server | 2026-08-21 | 4 Medium |
| Adaguc-server is an open source geographical information system to visualize, combine, compare and share real-time meteorological, climatological and remote sensing data via OGC standards. Versions prior to 7.2.2 crash with a memory-safety fault when it parses a GeoJSON document whose geometry contains a malformed coordinate. The coordinate parser in `adagucserverEC/CConvertGeoJSON.cpp` indexes `pt.u.array.values[0]` and `pt.u.array.values[1]` and uses `polygon.u.array.length` as a loop bound without first validating the JSON node type or the coordinate length. A coordinate that is an empty array, a one-element array, a scalar, or `null` leads to an out-of-bounds heap read or a NULL pointer dereference. The same unchecked pattern is present in four geometry branches: `Polygon`, `LineString`, `MultiLineString` and `MultiPolygon`. The vulnerable parser runs whenever the server processes a local GeoJSON file, either a configured GeoJSON dataset or a GeoJSON file exposed through the `AutoResource` feature and requested by an unauthenticated WMS request. A crafted GeoJSON file reliably crashes the backend process that handles that request. Version 7.2.2 patches the vulnerability. | ||||
| CVE-2026-16817 | 1 Ibm | 3 Aix, Powervm Vios, Vios | 2026-08-20 | 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-2026-68901 | 1 Wekan | 1 Wekan | 2026-08-19 | 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-2026-68362 | 1 Linux | 1 Linux Kernel | 2026-08-19 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix NULL pointer dereference in ath11k_hal_srng_access_begin In ATH11K_QMI_EVENT_FW_READY, ATH11K_FLAG_REGISTERED is set unconditionally even when ath11k_core_qmi_firmware_ready() fails. This leaves the driver in an inconsistent state where initialization is considered complete although the firmware ready handling did not finish successfully. During the subsequent SSR, the driver enters the restart path based on this incorrect state and dereferences uninitialized srng members, resulting in a NULL pointer dereference.

| CVE-2020-1069 | 1 Microsoft | 6 Sharepoint Enterprise Server, Sharepoint Foundation, Sharepoint Foundation 2013 and 3 more | 2026-08-19 | 8.8 High |
| A remote code execution vulnerability exists in Microsoft SharePoint Server when it fails to properly identify and filter unsafe ASP.Net web controls. An authenticated attacker who successfully exploited the vulnerability could use a specially crafted page to perform actions in the security context of the SharePoint application pool process. To exploit the vulnerability, an authenticated user must create and invoke a specially crafted page on an affected version of Microsoft SharePoint Server. The security update addresses the vulnerability by correcting how Microsoft SharePoint Server handles processing of created content. | ||||
| CVE-2026-68327 | 1 Linux | 1 Linux Kernel | 2026-08-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wan: wanxl: Only reset hardware after BAR mapping wanxl_pci_init_one() stores the freshly allocated card in driver data before the PLX BAR is mapped. Several early probe failures then unwind through wanxl_pci_remove_one(), including failure to allocate the coherent status area or to restore the DMA mask. wanxl_pci_remove_one() unconditionally calls wanxl_reset(), and wanxl_reset() dereferences card->plx. On those early failures card->plx is still NULL, so the error path can dereference a NULL MMIO pointer. Only issue the hardware reset once the BAR mapping exists. The remaining cleanup in wanxl_pci_remove_one() already checks whether later resources were allocated. This issue was found by a static analysis checker and confirmed by manual source review. | ||||
| CVE-2026-68310 | 1 Linux | 1 Linux Kernel | 2026-08-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: guard HE capability lookups mt7915_mcu_bss_he_tlv() and mt7915_mcu_sta_bfer_tlv() both run after checking HE support, then dereference the HE PHY capability returned by mt76_connac_get_he_phy_cap(). That helper can return NULL when no capability entry matches the vif type. Fetch the capability before appending the TLV and skip the HE-specific setup when no matching capability is available. | ||||
| CVE-2026-68195 | 1 Linux | 1 Linux Kernel | 2026-08-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses PKT_TYPE_TXRX_NOTIFY is an mmio-only event, but mt7615_rx_check() and mt7615_queue_rx_skb() dispatch it to mt7615_mac_tx_free() on every bus. mt7615_mac_tx_free() cleans the DMA tx queues with mt76_queue_tx_cleanup(), which calls queue_ops->tx_cleanup(). Only the mmio queue ops implement that callback; on the mt7663 USB and SDIO buses it is NULL, so a TXRX_NOTIFY there calls a NULL pointer in the RX worker. Same defect as the mt7921 and mt7925 patches in this series. Drop the event on non-mmio buses via mt76_is_mmio(), as in commit 5683e1488aa9 ("wifi: mt76: connac: do not check WED status for non-mmio devices"). | ||||

| In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev If the mmio_pipe_open() fails to find a PCI device, the hiter->dev will be assigned to NULL. The mmiotrace read() function dereferences the hiter->dev if hiter exists. Change the test of the read to not only check hiter being NULL, but also the hiter->dev before dereferencing it. | ||||
| CVE-2023-29539 | 2 Mozilla, Redhat | 10 Firefox, Firefox Esr, Firefox Mobile and 7 more | 2026-08-19 | 8.8 High |
| When handling the filename directive in the Content-Disposition header, the filename would be truncated if the filename contained a NULL character. This could have led to reflected file download attacks potentially tricking users to install malware. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10. | ||||
| CVE-2026-73502 | 1 Getkin | 1 Kin-openapi | 2026-08-18 | 5.3 Medium |
| kin-openapi is a Go project for handling OpenAPI files. From 0.2.0 until 0.144.0, openapi3filter.ValidateRequest can encounter a NULL-pointer-dereference denial of service when an operation declares a content parameter whose application/json media type has no schema. In openapi3filter/req_resp_decoder.go, the default defaultContentParameterDecoder dereferences mt.Schema.Value without checking whether mt.Schema is nil, even though doc.Validate() accepts the document under OpenAPI 3.0.x and 3.1.x. A single unauthenticated request supplying the parameter value can panic request validation, causing an aborted request with log growth in the common synchronous net/http path or a full process crash in integrations without recovery. This issue is fixed in version 0.144.0. | ||||
| CVE-2026-17574 | 1 Hdfgroup | 1 Hdf5 | 2026-08-18 | 5.5 Medium |
| HDF5 contains a NULL pointer dereference vulnerability. Processing a crafted HDF5 file containing an attribute with an invalid variable-length datatype type field may cause the application to crash when the attribute is read. | ||||

The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. | ||||
| CVE-2026-64140 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference in proc_show_files() When a SMB2 client opens a file with a durable v2 handle and then issues SMB2 SESSION_LOGOFF, session_fd_check() clears fp->tcon = NULL on the reconnectable file pointer but leaves the fp registered in global_ft.idr until the durable scavenger fires (up to fp->durable_timeout seconds later). During that window any read of /proc/fs/ksmbd/files (mode 0400) panics the kernel because proc_show_files() walks global_ft.idr and unconditionally dereferences fp->tcon->id with no NULL guard. Reproducer requires only a successful SMB2 SESSION_SETUP and a share configured with 'durable handles = yes'.

| CVE-2026-64141 | 1 Linux | 1 Linux Kernel | 2026-08-18 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix null pointer dereference in compare_guid_key() session_fd_check() walks the per-inode m_op_list during durable-handle session teardown and sets op->conn = NULL for every opinfo whose conn matched the closing session's connection. The matching opinfo, however, stays linked in its per-ClientGuid lease_table_list entry's lb->lease_list because destroy_lease_table() only runs on full TCP-connection teardown, not on SESSION_LOGOFF. If the same TCP connection then negotiates a fresh session with the same ClientGuid (ClientGuid is bound to NEGOTIATE, not the session, and is unchanged across LOGOFF + SETUP) and issues a SMB2 CREATE with a lease context on a different inode, find_same_lease_key() walks lb->lease_list, reaches the stale opinfo, and calls compare_guid_key(), which unconditionally dereferences opinfo->conn->ClientGUID. The conn pointer is NULL and the kernel panics. Reproducer requires only a successful SMB2 SESSION_SETUP and a share configured with 'durable handles = yes'. KASAN report on mainline 70390501d194: general protection fault, probably for non-canonical address 0xdffffc0000000069: 0000 [#1] SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000348-0x000000000000034f] Workqueue: ksmbd-io handle_ksmbd_work RIP: 0010:bcmp+0x5b/0x230 Call Trace: compare_guid_key+0x4b/0xd0 find_same_lease_key+0x324/0x690 smb2_open+0x6aea/0x8e60 handle_ksmbd_work+0x796/0xee0 ...
