| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Defer sub-object cleanup in export put callbacks
svc_export_put() calls path_put() and auth_domain_put() immediately
when the last reference drops, before the RCU grace period. RCU
readers in e_show() and c_show() access both ex_path (via
seq_path/d_path) and ex_client->name (via seq_escape) without
holding a reference. If cache_clean removes the entry and drops the
last reference concurrently, the sub-objects are freed while still
in use, producing a NULL pointer dereference in d_path.
Commit 2530766492ec ("nfsd: fix UAF when access ex_uuid or
ex_stats") moved kfree of ex_uuid and ex_stats into the
call_rcu callback, but left path_put() and auth_domain_put() running
before the grace period because both may sleep and call_rcu
callbacks execute in softirq context.
Replace call_rcu/kfree_rcu with queue_rcu_work(), which defers the
callback until after the RCU grace period and executes it in process
context where sleeping is permitted. This allows path_put() and
auth_domain_put() to be moved into the deferred callback alongside
the other resource releases. Apply the same fix to expkey_put(),
which has the identical pattern with ek_path and ek_client.
A dedicated workqueue scopes the shutdown drain to only NFSD
export release work items; flushing the shared
system_unbound_wq would stall on unrelated work from other
subsystems. nfsd_export_shutdown() uses rcu_barrier() followed
by flush_workqueue() to ensure all deferred release callbacks
complete before the export caches are destroyed.

| An issue was discovered in the Wi-Fi driver in Samsung Mobile Processor and Wearable Processor Exynos 980, 850, 1080, 1280, 1330, 1380, 1480, 1580, W920, W930, and W1000. Improper synchronization on a global variable leads to a use-after-free. An attacker can trigger a race condition by invoking an ioctl function concurrently from multiple threads. |
| The YOP Poll plugin for WordPress is vulnerable to a race condition in all versions up to, and including, 6.5.26. This is due to improper restrictions on the add() function. This makes it possible for unauthenticated attackers to place multiple votes on a single poll even when the poll is set to one vote per person. |
| The LWS Cleaner plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'lws_cl_delete_file' function in all versions up to, and including, 2.4.1.3. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). |
| The WP-DownloadManager plugin for WordPress is vulnerable to arbitrary file deletion due to lack of restriction on the directory a file can be deleted from in all versions up to, and including, 1.68.10. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This vulnerability can be paired with CVE-2025-4798 to delete any file within the WordPress root directory. |
| The WordPress User Extra Fields plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the save_fields() function in all versions up to, and including, 16.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). |
| The Fancy Product Designer plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 6.4.8. This is due to a time-of-check/time-of-use (TOCTOU) race condition in the 'url' parameter of the fpd_custom_uplod_file AJAX action. The plugin validates the URL by calling getimagesize() first, then later retrieves the same URL using file_get_contents(). This makes it possible for unauthenticated attackers to exploit the timing gap to perform SSRF attacks by serving a valid image during validation, then changing the response to redirect to arbitrary internal or external URLs during the actual fetch. |
| The BeeTeam368 Extensions plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.3.4 via the handle_remove_temp_file() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform actions on files outside of the originally intended directory. This vulnerability can be used to delete the wp-config.php file, which can be leveraged into a site takeover. |
| The Everest Forms (Pro) plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_entry_files() function in all versions up to, and including, 1.9.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The vulnerability requires an admin to trigger the deletion via deletion of a form entry and cannot be carried out by the attacker alone. |
| The NinjaScanner – Virus & Malware scan plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'nscan_ajax_quarantine' and 'nscan_quarantine_select' functions in all versions up to, and including, 3.2.5. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, including files outside the WordPress root directory. |
| The atec Debug plugin for WordPress is vulnerable to arbitrary file read in all versions up to, and including, 1.2.22 via the 'custom_log' parameter. This makes it possible for authenticated attackers, with Administrator-level access and above, to view the contents of files outside of the originally intended directory. |
| The JetFormBuilder plugin for WordPress is vulnerable to arbitrary file read via path traversal in all versions up to, and including, 3.5.6.2. This is due to the 'Uploaded_File::set_from_array' method accepting user-supplied file paths from the Media Field preset JSON payload without validating that the path belongs to the WordPress uploads directory. Combined with an insufficient same-file check in 'File_Tools::is_same_file' that only compares basenames, this makes it possible for unauthenticated attackers to exfiltrate arbitrary local files as email attachments by submitting a crafted form request when the form is configured with a Media Field and a Send Email action with file attachment. |
| The atec Debug plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation on the 'debug_path' parameter in all versions up to, and including, 1.2.22. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). |
| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, apps that register an asynchronous session.setPermissionRequestHandler() may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invoking the stored callback dereferences freed memory, which may lead to a crash or memory corruption. Apps that do not set a permission request handler, or whose handler responds synchronously, are not affected. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8. |
| A race condition was addressed with improved handling of symbolic links. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Sonoma 14.8.4, macOS Tahoe 26.3, visionOS 26.3. A shortcut may be able to bypass sandbox restrictions. |
| util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privileges via fork() + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0) without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the source file with a symlink pointing to any root-owned file or device during the race window, causing the SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized read access to root-protected files and block devices, including backup images, disk volumes, and any file containing a valid filesystem. This issue has been patched in version 2.41.4. |
| A race condition was addressed with additional validation. This issue is fixed in macOS Sequoia 15.1. An app may be able to break out of its sandbox. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: synaptics - fix crash when enabling pass-through port
When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.
Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash. |

Bluetooth: Fix hci_suspend_sync crash
If hci_unregister_dev() frees the hci_dev object but hci_suspend_notifier
may still be accessing it, it can cause the program to crash.
