In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: Fix inquiry cache use-after-free The sync command worker holds hdev->req_lock, but inquiry-cache updates and flushes use hdev->lock. Both hci_acl_create_conn_sync() and hci_stop_discovery_sync() look up entries and read their fields without taking hdev->lock. After either lookup returns, a concurrent HCIINQUIRY ioctl can acquire hdev->lock and flush the cache, freeing the entry. The worker then reads the freed entry while preparing a create-connection or remote-name-cancel command. The list traversal also races with cache updates and removal.

Oct 18, 2026In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Apply the fine-grained UNDEFs without FEAT_FGT FGUs don't actually require harCVE-2026-98713 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Apply the fine-grained UNDEFs without FEAT_FGT FGUs don't actually require hardware support, so don't gate fgt trap config insertion on FGT. This is the only action required to allow FGUs always, as kvm_calculate_traps() already computes the FGU bits with or without FEAT_FGT. This also fixes a spurious WARN when a TLBI OS is run on a guest in vEL1 without FEAT_TLBIOS on non FEAT_FGT hardware. In this configuration the course-grained HCR_EL2.TTLBOS trap reaches the handler handle_tlbi_el1(), which expects an EL1 TLBI only from vEL2. With FGUs enabled the UNDEF will be injected without needing the specific handler. [oliver: Take Wei-Lin's suggested changelog]

Oct 18, 2026In the Linux kernel, the following vulnerability has been resolved: perf: Require kernel access for text poke events Perf events with exclude_kernel=1 can be CVE-2026-98655 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: perf: Require kernel access for text poke events Perf events with exclude_kernel=1 can be opened without kernel perf access. However, exclude_kernel does not suppress text-poke sideband records. Every PERF_RECORD_TEXT_POKE is marked PERF_RECORD_MISC_KERNEL and contains a raw kernel instruction address. An unprivileged task can therefore open and mmap a task-local software event with text_poke=1. Both opening a count-only tracepoint event and configuring UDP GRO for ESP-in-UDP cause updates to inline static calls; the observer receives the relocated addresses of the modified instructions. For a known kernel image, any such address reveals the runtime kernel text base despite KASLR. Call perf_allow_kernel() whenever attr.text_poke is set, regardless of exclude_kernel. Events that neither monitor kernel execution nor request text-poke records retain their existing permissions.

Oct 18, 2026In the Linux kernel, the following vulnerability has been resolved: writeback: report a Tasks-RCU quiescent state per cgwb drain pass cleanup_offline_cgwbs_woCVE-2026-98536 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: writeback: report a Tasks-RCU quiescent state per cgwb drain pass cleanup_offline_cgwbs_workfn() drains a dying cgwb by calling cleanup_offline_cgwb() until it returns false, with a cond_resched() between passes. On a CONFIG_PREEMPTION kernel that cond_resched() does nothing: _cond_resched() is a plain "return 0", and under PREEMPT_DYNAMIC the full and lazy modes disable it. Since commit 7dadeaa6e851 ("sched: Further restrict the preemption modes") those are the only two models on the architectures with PREEMPT_LAZY support, arm64 and x86 among them, so the drain loop never reports a Tasks-RCU quiescent state. A worker draining a cgwb with millions of attached inodes runs for minutes. On a 6.18 arm64 host in lazy mode the cgwb worker drained one dying cgroup's writeback domain for over 11 minutes. A BPF program unlink (bpf_trampoline_unlink_prog -> bpf_trampoline_update -> unregister_ftrace_direct -> ftrace_shutdown -> synchronize_rcu_tasks()) waited on that grace period while holding the trampoline mutex, 42 tasks queued behind it in D state, and the hung task detector fired at 614 s and panicked the host.

In the Linux kernel, the following vulnerability has been resolved: gpio: cdev: fix kernel stack leak to user-space in error path If we fail to acquire the GPIO chip guard in gpio_desc_to_lineinfo(), we return immediately before zeroing the info struct we'll end up passing to the user-space later in lineinfo_get_v1(). This may leak the kernel stack contents. Make gpio_desc_to_lineinfo() return int so that the -ENODEV returned on failure to acquire the guard can be propagated to the callers. While not strictly necessary: move the memset() before trying to acquire the SRCU read lock too for good measure.

Oct 16, 2026Quick PayPal Payments: Payment Button & Form: Stored Cross-Site ScriptingCVE-2026-110017 · WordPress plugins & themes · reported by WordfenceMedium 6.4
The Quick PayPal Payments: Payment Button & Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form' parameter in all versions up to, and including, 6.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because wp_kses_post strips only HTML tags, a quote-breaking payload containing no angle brackets survives post save intact, and the injected script fires for every viewer of the post — including higher-privileged Editors and Administrators who routinely preview a Contributor's pending content.

The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 10.3.1 via attacker-controlled attributes of the [lifterlms_checkout] shortcode. This is due to the llms_get_template() helper performing extract() on the shortcode attribute array before resolving the template path, which allows the attacker-supplied 'template_name' and 'default_path' shortcode attributes to overwrite the function's local parameters and ultimately control the path passed to a PHP include. This makes it possible for authenticated attackers, with Instructor-level access and above, to include and execute arbitrary files on the server, that can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where files with safe extensions containing attacker-controlled content can be uploaded and included.

The SimpleForm – Form Maker to Chat Apps with Quiz, Poll and Multi Lead Notifications plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.10.0 This is due to the `wp_ajax_nopriv_simpleform_wp_register` AJAX action lacking any capability check for role assignment and the `save_custom_fields_to_user_meta()` function using an exclusion list that omits `wp_capabilities`, combined with `get_form_settings()` returning a hard-coded defaults array that unconditionally enables meta writing regardless of the supplied `form_id`. This makes it possible for unauthenticated attackers to create a new Administrator-level WordPress account by supplying `wp_capabilities[administrator]=1` alongside standard registration fields. The nonce required by the endpoint is publicly emitted into the `front_end_data` JavaScript object on every front-end page via `wp_enqueue_scripts`, making it trivially obtainable by any unauthenticated visitor before submitting the malicious request.

Oct 13, 2026Squid is a caching proxy for the Web.CVE-2026-61642 · Other software · squid-cache · reported by GitHubHigh 7.7
Squid is a caching proxy for the Web. From 3.3.0.1 to before 7.6, due to an improper enforcement of behavioral workflow bug, Squid is vulnerable to a Request Smuggling attack against HTTP/1.1 Transfer-Encoding. HTTP header parsing (`src/HttpHeader.cc`) accepted the bare` Transfer-Encoding:` identity form, which the HTTP specification prohibits because any transfer coding must be wrapped within chunked encoding. This problem allows a trusted client to perform an HTTP Request Smuggling attack when HTTP/1.1 is used, bypassing security mechanisms that may be in place between attacker and Squid. When there is an HTTP cache operating prior to the affected Squid, this Request Smuggling attack also allows the attacker to poison that web cache and store arbitrary malicious content at any URL for delivery to other clients' future requests. This issue is fixed in version 7.6.

Oct 13, 2026The authorization middleware of the WMS MobileServer fails to require authentication in two distinct cases.CVE-2026-89309 · Other software · JTL SW GmbH · reported by a6d3dc9e-0591-4a13-bce7-0f5b31ff6158Critical 10
The authorization middleware of the WMS MobileServer fails to require authentication in two distinct cases. First, it only requires an Authorization header for GET and HEAD requests; requests using any other HTTP method are processed without an authentication check. Second, for any HTTP method including GET and HEAD, a request carrying a malformed or non-bearer Authorization header is passed through without a valid token being required. The middleware does validate a token whenever a well-formed one is present, but in these two cases it does not require one. A remote attacker with network access to the service can therefore invoke API functionality without valid credentials.
