| The issue was addressed with improved checks. This issue is fixed in iOS 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, visionOS 2.4, watchOS 11.4. An attacker on the local network may cause an unexpected app termination. |
| A null pointer dereference was addressed with improved input validation. This issue is fixed in iOS 18.3 and iPadOS 18.3, iPadOS 17.7.6, macOS Sequoia 15.3, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An attacker on the local network may be able to cause a denial-of-service. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix memory leaks and NULL deref in smb2_lock()
smb2_lock() has three error handling issues after list_del() detaches
smb_lock from lock_list at no_check_cl:
1) If vfs_lock_file() returns an unexpected error in the non-UNLOCK
path, goto out leaks smb_lock and its flock because the out:
handler only iterates lock_list and rollback_list, neither of
which contains the detached smb_lock.
2) If vfs_lock_file() returns -ENOENT in the UNLOCK path, goto out
leaks smb_lock and flock for the same reason. The error code
returned to the dispatcher is also stale.
3) In the rollback path, smb_flock_init() can return NULL on
allocation failure. The result is dereferenced unconditionally,
causing a kernel NULL pointer dereference. Add a NULL check to
prevent the crash and clean up the bookkeeping; the VFS lock
itself cannot be rolled back without the allocation and will be
released at file or connection teardown.
Fix cases 1 and 2 by hoisting the locks_free_lock()/kfree() to before
the if(!rc) check in the UNLOCK branch so all exit paths share one
free site, and by freeing smb_lock and flock before goto out in the
non-UNLOCK branch. Propagate the correct error code in both cases.
Fix case 3 by wrapping the VFS unlock in an if(rlock) guard and adding
a NULL check for locks_free_lock(rlock) in the shared cleanup.

| In the Linux kernel, the following vulnerability has been resolved:
net: lan966x: fix page_pool error handling in lan966x_fdma_rx_alloc_page_pool()
page_pool_create() can return an ERR_PTR on failure. The return value
is used unconditionally in the loop that follows, passing the error
pointer through xdp_rxq_info_reg_mem_model() into page_pool_use_xdp_mem(),
which dereferences it, causing a kernel oops.
Add an IS_ERR check after page_pool_create() to return early on failure. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: allocate rx skb before consuming bytes
pn532_receive_buf() reports the number of accepted bytes to the serdev
core. The current code consumes bytes into recv_skb and may already hand
a complete frame to pn533_recv_frame() before allocating a fresh receive
buffer.
If that alloc_skb() fails, the callback returns 0 even though it has
already consumed bytes, and it leaves recv_skb as NULL for the next
receive callback. That breaks the receive_buf() accounting contract and
can also lead to a NULL dereference on the next skb_put_u8().
Allocate the receive skb lazily before consuming the next byte instead.
If allocation fails, return the number of bytes already accepted. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: cp2615: fix serial string NULL-deref at probe
The cp2615 driver uses the USB device serial string as the i2c adapter
name but does not make sure that the string exists.
Verify that the device has a serial number before accessing it to avoid
triggering a NULL-pointer dereference (e.g. with malicious devices). |
| In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Fix missing NULL checks for kstrdup()
1. Replace "of_find_node_by_path("/")" with "of_root" to avoid multiple
calls to "of_node_put()".
2. Fix a potential kernel oops during early boot when memory allocation
fails while parsing CPU model from device tree. |
| Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.20 and 6.13.0, manipulating query parameters on Control Panel and REST API endpoints, or arguments in GraphQL queries, could result in the loss of content, assets, and user accounts. The Control Panel requires authentication with minimal permissions in order to exploit. e.g. "view entries" permission to delete entries, or "view users" permission to delete users, etc. The REST and GraphQL API exploits do not require any permissions, however neither are enabled by default. In order to be exploited, they would need to be explicitly enabled with no authentication configured, and the specific resources enabled too. Sites that enable the REST or GraphQL API without authentication should treat patching as critical priority. This has been fixed in 5.73.20 and 6.13.0. |
| An attacker can send replies that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service. Cookies are disabled by default. |
| An RPZ sent by a malicious authoritative server can result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service. |
| If you use the zoneToCache function with a malicious authoritative server, an attacker can send a zone that result in a null pointer dereference, caused by a missing consistency check and leading to a denial of service. |
| OpenClaw before 2026.3.22 contains an access control bypass vulnerability in the allowProfiles feature that allows attackers to circumvent profile restrictions through persistent profile mutation and runtime profile selection. Remote attackers can exploit this by manipulating browser proxy profiles at runtime to access restricted profiles and bypass intended access controls. |
| Firebird is an open-source relational database management system. In versions prior to 6.0.0, 5.0.4, 4.0.7 and 3.0.14, when processing an op_slice network packet, the server passes an unprepared structure containing a null pointer to the SDL_info() function, resulting in a null pointer dereference and server crash. An unauthenticated attacker can trigger this by sending a crafted packet to the server port. This issue has been fixed in versions 6.0.0, 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when the server receives an op_crypt_key_callback packet without prior authentication, the port_server_crypt_callback handler is not initialized, resulting in a null pointer dereference and server crash. An unauthenticated attacker who knows only the server's IP and port can exploit this to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/client: Do not destroy NULL modes
'modes' in drm_client_modeset_probe may fail to kcalloc. If this
occurs, we jump to 'out', calling modes_destroy on it, which
dereferences it. This may result in a NULL pointer dereference in the
error case. Prevent that. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: pidff: Fix condition effect bit clearing
As reported by MPDarkGuy on discord, NULL pointer dereferences were
happening because not all the conditional effects bits were cleared.
Properly clear all conditional effect bits from ffbit |
| The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to price manipulation via the 'tips' parameter in all versions up to, and including, 27.0. This is due to the plugin trusting a user-supplied input without server-side validation against the configured price. This makes it possible for unauthenticated attackers to submit a negative number to the 'tips' parameter, causing the total price to be reduced to zero. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: i801: Revert "i2c: i801: replace acpi_lock with I2C bus lock"
This reverts commit f707d6b9e7c18f669adfdb443906d46cfbaaa0c1.
Under rare circumstances, multiple udev threads can collect i801 device
info on boot and walk i801_acpi_io_handler somewhat concurrently. The
first will note the area is reserved by acpi to prevent further touches.
This ultimately causes the area to be deregistered. The second will
enter i801_acpi_io_handler after the area is unregistered but before a
check can be made that the area is unregistered. i2c_lock_bus relies on
the now unregistered area containing lock_ops to lock the bus. The end
result is a kernel panic on boot with the following backtrace;
