CVE-2026-76650 1 Tp-link 1 Tl-wr841n V14 2026-09-01 N/A
A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP state variable query requests. A specially crafted SOAP query may trigger unexpected termination or instability of the process hosting the UPnP service. Successful exploitation may result in a denial-of-service condition affecting UPnP discovery, state query, or related management functionality until the affected process is restarted or the device is rebooted.
CVE-2026-82926 1 Samsung Open Source 1 Mtower 2026-09-01 5.5 Medium
NULL pointer dereference vulnerability in Samsung Open Source mTower allows Pointer Manipulation. This issue affects mTower: before afef59aa6f55c5d5ebf9b14bc020bf1c2c37489a.
CVE-2026-20727 1 Intel 19 Intel Proset Wireless Wifi Software For Windows, Killer Wi-fi 6 Ax1650i\/s, Killer Wi-fi 6e Ax1675i\/s and 16 more 2026-09-01 8.6 High
Null pointer dereference for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
CVE-2026-82821 1 Flvmeta 1 Flvmeta 2026-08-31 4.3 Medium
A vulnerability was determined in FLVMeta up to 1.2.2. Affected by this vulnerability is the function amf_object_get of the file src/amf.c of the component AMF Object Parsing. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. Patch name: 52642f7dfb76ec7334016622dde60b1ae963d79b. To fix this issue, it is recommended to deploy a patch. The project maintainer doubts the security impact: "While I acknowledged the bugs and provided fixes, I have yet to see any way to exploit these alleged vulnerabilities."
CVE-2026-26456 2026-08-31 7.5 High
A null pointer dereference vulnerability exists in the server-side session management logic of ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5. The issue is caused by a race condition between the request dispatch thread and the session cleanup thread when accessing shared session list nodes without proper synchronization.
CVE-2026-81490 1 Mongodb 1 Bi Connector 2026-08-31 7.7 High
A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.
CVE-2026-76922 1 Wireshark 1 Wireshark 2026-08-31 5.5 Medium
Bluetooth BR/EDR FHS protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service
CVE-2026-38344 1 Ffmpeg 1 Ffmpeg 2026-08-31 7.5 High
A NULL pointer dereference in the get_min_buffer_size function (/libswscale/slice.c) of FFmpeg N-122528-gdd2976b9e1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted video file.
CVE-2026-30069 1 Free5gc 1 Free5gc 2026-08-31 7.5 High
A NULL pointer dereference in the UDMC registration handler component of free5gc v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying crafted payload.
CVE-2026-30072 1 Free5gc 1 Free5gc 2026-08-31 7.5 High
A NULL pointer dereference in the CDR processing path of free5gc v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying crafted payload.
CVE-2026-82803 1 Armink 1 Struct2json 2026-08-31 5.3 Medium
A vulnerability has been found in armink struct2json 1.0. This affects the function S2J_STRUCT_GET_string_ELEMENT in the library struct2json/inc/s2jdef.h of the component JSON Deserialization. The manipulation of the argument valuestring leads to null pointer dereference. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-76927 1 Wireshark 1 Wireshark 2026-08-31 4.7 Medium
H.245 protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service
CVE-2026-76928 1 Wireshark 1 Wireshark 2026-08-31 7.5 High
X.509IF protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service
CVE-2026-80677 1 Linux 1 Linux Kernel 2026-08-31 7.8 High
In the Linux kernel, the following vulnerability has been resolved: driver core: use READ_ONCE() for dev->driver in dev_has_sync_state() dev_has_sync_state() reads dev->driver twice without holding device_lock() -- once for the NULL check and once to dereference ->sync_state. Some callers only hold device_links_write_lock, which doesn't prevent a concurrent unbind from clearing dev->driver via device_unbind_cleanup(). Fix it by reading dev->driver exactly once with READ_ONCE(), pairing with the WRITE_ONCE() in device_set_driver().
CVE-2026-14324 2 Pipewire, Redhat 2 Pipewire, Enterprise Linux 2026-08-31 6.5 Medium
RAOP module accepts unbounded Content-Length values and does not check the pw_array_add() return.
CVE-2026-80614 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: net: emac: Fix NULL pointer dereference in emac_probe Move devm_request_irq() after devm_platform_ioremap_resource() so that dev->emacp is mapped before the interrupt handler can fire. An early interrupt hitting emac_irq() would dereference the NULL dev->emacp and crash. Also remove redundant error message. devm_platform_ioremap_resource() already returns an error message with dev_err_probe().
CVE-2026-80684 1 Linux 1 Linux Kernel 2026-08-29 9.3 Critical
In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Fix NULL dereference on AIBV allocation failure The airq_iv_create() can return NULL on failure, but the return value was never checked. If it fails, zdev->aibv will be NULL and fail when dereferenced in kvm_zpci_set_airq(). Add a NULL check and free the previously allocated AISB bit and zdev->aisb on failure.
CVE-2026-80646 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: ipv6: guard against possible NULL deref in __in6_dev_stats_get() dev_get_by_index_rcu() could return NULL if the original physical device is unregistered. Found by Sashiko.
CVE-2026-80631 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: btrfs: lzo: reject compressed segment that overflows the compressed input lzo_decompress_bio() validates each on-disk segment length seg_len only against the workspace cbuf size, not against the compressed input size (compressed_len, the total folio bytes of the bio). A crafted extent can carry a segment whose seg_len passes the cbuf check but runs past the end of the bio, so copy_compressed_segment() walks off the last folio: get_current_folio() then returns the NULL folio from bio_next_folio(), and with CONFIG_BTRFS_ASSERT disabled (default) folio_size(NULL) faults. BUG: KASAN: null-ptr-deref in lzo_decompress_bio (fs/btrfs/lzo.c:383) Read of size 8 at addr 0000000000000000 by task kworker/u8:1/29 Workqueue: btrfs-endio simple_end_io_work kasan_report (mm/kasan/report.c:590) lzo_decompress_bio (fs/btrfs/lzo.c:383) end_bbio_compressed_read (fs/btrfs/compression.c:1065) btrfs_bio_end_io (fs/btrfs/bio.c:135) btrfs_check_read_bio (fs/btrfs/bio.c:180 fs/btrfs/bio.c:285) simple_end_io_work process_one_work worker_thread Reject any segment whose payload would extend beyond compressed_len before copying it, treating it as corruption like the other on-disk validation failures in this function.
CVE-2026-80691 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: scsi: target: iblock: Fix wrong PR ops NULL check for PREEMPT/RELEASE In the iblock_execute_pr_out() function, PRO_PREEMPT, PRO_PREEMPT_AND_ABORT, and PRO_RELEASE all perform callback capability checks through ops->pr_clear. The error check allows unimplemented hooks to pass through the gate, resulting dereferencing a NULL function pointer. Check whether the hooks that need to be called are supported.
