| CVE-2026-31477 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 7.5 High |
| 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.

| CVE-2026-31646 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 5.5 Medium |
| 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. | ||||
| CVE-2026-31660 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 5.5 Medium |
| 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. | ||||
| CVE-2026-31549 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 5.5 Medium |
| 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). | ||||
| CVE-2026-31559 | 1 Linux | 1 Linux Kernel | 2026-04-27 | 5.5 Medium |
| 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. | ||||
| CVE-2026-41175 | 1 Statamic | 2 Cms, Statamic | 2026-04-27 | 8.1 High |
| 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. | ||||

| CVE-2026-41353 | 1 Openclaw | 1 Openclaw | 2026-04-25 | 8.1 High |
| 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. | ||||
| CVE-2026-28212 | 1 Firebirdsql | 1 Firebird | 2026-04-24 | 7.5 High |
| 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. | ||||
| CVE-2026-28224 | 1 Firebirdsql | 1 Firebird | 2026-04-24 | 8.2 High |
| 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. | ||||
| CVE-2026-23349 | 1 Linux | 1 Linux Kernel | 2026-04-24 | 5.5 Medium |

| CVE-2026-2519 | 2 Ladela, Wordpress | 2 Online Scheduling And Appointment Booking System – Bookly, Wordpress | 2026-04-24 | 5.3 Medium |
| 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. | ||||

| CVE-2026-23433 | 1 Linux | 1 Linux Kernel | 2026-04-23 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: arm_mpam: Fix null pointer dereference when restoring bandwidth counters When an MSC supporting memory bandwidth monitoring is brought offline and then online, mpam_restore_mbwu_state() calls __ris_msmon_read() via ipi to restore the configuration of the bandwidth counters. It doesn't care about the value read, mbwu_arg.val, and doesn't set it leading to a null pointer dereference when __ris_msmon_read() adds to it. This results in a kernel oops with a call trace such as: Call trace: __ris_msmon_read+0x19c/0x64c (P) mpam_restore_mbwu_state+0xa0/0xe8 smp_call_on_cpu_callback+0x1c/0x38 process_one_work+0x154/0x4b4 worker_thread+0x188/0x310 kthread+0x11c/0x130 ret_from_fork+0x10/0x20 Provide a local variable for val to avoid __ris_msmon_read() dereferencing a null pointer when adding to val. | ||||
