| CVE-2026-98356 | 1 Linux | 1 Linux Kernel | 2026-10-06 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: check create_singlethread_workqueue() in DCB setup bnxt_re_init_dcb_wq() ignores a failed allocation. The async DCB handler later calls queue_work() on the NULL pointer. | ||||
| CVE-2026-102169 | 2026-10-06 | 6.5 Medium | ||
| On affected Arista Wi-Fi access points with Captive Portal enabled, an unauthenticated wireless client connected to a captive-portal-enabled SSID can crash the portal service with a crafted HTTP request. The service automatically restarts, but a sustained low-rate attack can cause a persistent denial of service of the captive portal. Remote code execution is not possible. | ||||
| CVE-2017-20285 | 1 Ingydotnet | 1 Yaml | 2026-10-06 | 9.1 Critical |
| YAML versions before 1.30 for Perl allow a loaded document to trigger the DESTROY method of arbitrary classes. A perl/hash:Class tag blesses a hash into the class it names. The document supplies the object's fields, and Perl calls DESTROY when it goes out of scope. What DESTROY does depends on the classes the process has loaded. With File::Temp::Dir from core Perl, it can delete a directory tree the document names. | ||||
| CVE-2026-98259 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: fs/dax: check zero or empty entry before converting xarray entry Calling dax_to_folio() with empty entry causes kernel panic below when booting a VM with DAX enabled storage. This patch checks empty entry before calling dax_to_folio() on dax_associate_entry(), dax_disassociate_entry(), and dax_busy_page(). Commit 98c183a4fccf ("fs/dax: don't disassociate zero page entries") added guards in the associate and disassociate paths, but the guards still come after dax_to_folio(), and dax_busy_page() still has the same problem.

| CVE-2026-86128 | 1 Watchguard | 2 Fireware, Fireware Os | 2026-10-06 | 7.5 High |
| A NULL pointer dereference vulnerability in Fireware OS's NetFlow packet-processing feature allows a remote, unauthenticated attacker to cause a denial of service by sending a specially crafted IPv6 packet. | ||||
| CVE-2026-19026 | 1 Hdfgroup | 1 Hdf5 | 2026-10-06 | 5.5 Medium |
| H5Z__filter_nbit in H5Znbit.c in HDF5 prior to 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools. | ||||
| CVE-2026-98285 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: bridge: vlan: fix bugs caused by switchdev deletion errors Allowing switchdev to prevent vlan deletion and error out in __vlan_del could cause multiple different issues - inconsistent state, memory leaks when flushing, NULL pointer dereference on bridge error when flushing. It doesn't make sense to allow it to stop __vlan_del, so log the error and continue with software vlan deletion. This is also consistent with 8021q behaviour. | ||||
| CVE-2026-86136 | 1 Watchguard | 2 Fireware, Fireware Os | 2026-10-06 | 8.1 High |
| A missing authorization vulnerability in the wgagent management daemon's session initialization function allows an authenticated, low-privileged user (including a read-only or guest administrator account) to crash the wgagent process and read arbitrary files accessible to the daemon by submitting a specially crafted management API request. | ||||
| CVE-2026-98308 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: trace PCM open only after assigning a stream Stream assignment can fail when hardware streams are exhausted. Move the tracepoint after the NULL check because its payload accesses the assigned stream tag. Detected by static analysis and reviewed with AI-assisted source auditing. | ||||
| CVE-2026-9032 | 1 Tp-link | 2 Tapo C120 V1, Tapo C200 V5 | 2026-10-06 | N/A |
| Tapo C120 v1 and C200 v5 contain a NULL pointer dereference in the HTTPS onboarding connect request parser. The interface is reachable without authentication after initial setup and does not validate that a password field is present for certain authentication and encryption parameter combinations, allowing a malformed request from the same local network to crash the HTTPS service Successful exploitation may temporarily make HTTPS management functions unavailable. Repeated malformed requests may sustain the denial-of-service condition, and recovery may in some cases require a device reboot. | ||||
| CVE-2026-64040 | 1 Linux | 1 Linux Kernel | 2026-10-06 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix error return when vfs_mkdir() fails When vfs_mkdir() fails, the error code is not extracted from the returned error pointer. This causes mkdir_error to be reached with ret=0, which leads to returning ERR_PTR(0) (NULL) instead of a proper error pointer. Fix this by extracting the error code from the error pointer when vfs_mkdir() fails. | ||||
| CVE-2026-86134 | 1 Watchguard | 2 Fireware, Fireware Os | 2026-10-06 | 7.5 High |
| A NULL pointer dereference vulnerability in the WatchGuard Fireware OS authentication process allows a remote, unauthenticated attacker to crash the management daemon by sending a specially request to the login interface, resulting in a denial of service. | ||||
| CVE-2026-98346 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: don't get the radio mask for netdev-less wdevs cfg80211_calculate_bi_data() calls rdev_get_radio_mask() with wdev->netdev, which can be NULL and then crashes in mac80211. To avoid that, invert the order of checks since wdev->netdev is always valid for beaconing interfaces. | ||||
| CVE-2026-98268 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: perf: Fix null pointer access in is_include_guest_event() A typical module unload occurring event when there is an active perf connection leads to freeing of the pmu pointer. The call log is something like: .. __pmu_detach_event pmu_detach_event pmu_detach_events perf_pmu_unregister .. __pmu_detach_event() sets event->pmu to null. When the perf connection finally is closed, the following stack trace is observed: Oops: general protection fault, kernel NULL pointer dereference ... RIP: 0010:_free_event+0x3e/0x370 ... Call Trace: ... perf_event_release_kernel+0x260/0x2d0 perf_release+0x12/0x20 A call to mediated_pmu_unaccount_event() inside _free_event() is the root cause of this crash. Adding a check inside is_include_guest_event() ensures we don't accidentally access a null pmu ptr. In addition to this, we will now call mediated_pmu_unaccount_event() before clearing the pmu ptr so that nr_include_guest_events counts are maintained correctly. | ||||
| CVE-2026-98202 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - fix GPF in suspend and resume when unbound Transport drivers (such as rmi_i2c and rmi_spi) invoke rmi_driver_suspend() and rmi_driver_resume() on their child rmi_dev device during system power management events. However, transport drivers are fully registered and operational even if the physical RMI driver failed to bind or probe the rmi_dev device. When rmi_driver_suspend() or rmi_driver_resume() is called on an unbound rmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or rmi_enable_irq() without driver data attached causes a NULL pointer dereference and General Protection Fault when attempting to lock data->enabled_mutex. Fix this by checking if driver data is attached to rmi_dev in rmi_driver_suspend() and rmi_driver_resume(), exiting early if no driver data is present. | ||||
| CVE-2026-73547 | 1 Envoyproxy | 1 Envoy | 2026-10-06 | 7.5 High |
| Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's ext_authz filter assumes that a request contains a :path pseudoheader when applying query_parameters_to_set or query_parameters_to_remove from an authorization response. A path-less CONNECT request makes request_headers_->Path() return null, and Filter::onComplete dereferences that pointer while parsing the query string. An unauthenticated downstream client can crash the Envoy process when the filter and authorization response use query-parameter mutation. The relevant scope boundary is that the deployment must accept path-less CONNECT and configure ext_authz query-parameter mutation. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1. | ||||
| CVE-2026-66269 | 1 Dell | 5 Dell Openmanage Server Administrator Managed Node (patch) For Windows, Dell Openmanage Server Administrator Managed Node For Rhel 8.10, Dell Openmanage Server Administrator Managed Node For Rhel 9.4 and 2 more | 2026-10-06 | 7.3 High |
| Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains a Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass. | ||||
| CVE-2026-98182 | 1 Linux | 1 Linux Kernel | 2026-10-06 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: refuse to make a monitor active when it has no queue A monitor interface only gets a TXQ if it's created active, and one can't be added later. Setting the flag on a down interface is still allowed, so the driver is handed a monitor with no queue. ath9k dereferences it: BUG: kernel NULL pointer dereference, address: 0000000000000066 RIP: 0010:ath_tx_node_init+0x49/0x170 [ath9k] ath9k_add_interface+0x10c/0x140 [ath9k] drv_add_interface+0x54/0x250 [mac80211] ieee80211_do_open+0x32f/0x800 [mac80211] Reached with CAP_NET_ADMIN by "iw dev X set monitor active" followed by "ip link set X up". RTNL is held, so netlink operations block behind it. Refuse the flag when there is no queue to give. | ||||
| CVE-2026-105782 | 1 Scrapy | 1 Scrapy | 2026-10-06 | 7.5 High |
| Scrapy is a high-level web crawling and scraping framework for Python. From 1.4.0 until 2.14.2, RefererMiddleware in scrapy/spidermiddlewares/referer.py treated a Referrer-Policy response-header value that resembled a Python import path as a referrer policy class, imported the referenced object, and called it. A malicious website could supply a callable such as sys.exit and terminate a crawler processing the response. This issue is fixed in version 2.14.2. | ||||
| CVE-2026-93316 | 1 Moby | 1 Buildkit | 2026-10-05 | 6.5 Medium |
| If BuildKit daemon is started with --cdi-disabled it can lead to daemon panic when builds try to use CDI devices. This can happen maliciously or by accident. | ||||
