The Ministry of Education is committed to bring out the best in every child by providing a variety of learning opportunities, nurturing the whole child holistically. The broad-based education exposes each child to different possibilities and ensures a strong foundation for learning in a variety of domains. MOE has created a variegated education landscape with diverse pathways, aimed at helping our children cultivate qualities such as creativity, confidence, compassion and resilience – life skills essential in a rapidly changing world. They also learn values such as respect, responsibility, integrity, care, and harmony; all of which are important for safeguarding our cohesive and harmonious multi-racial and multi-cultural society. Collectively, these are the Education Ministry’s efforts to ensure that all our students acquire a broad and deep foundation for a lifelong journey of learning.
Founded in 1965 in Sweden, EF (Education First) is a global association of education companies that shares a common mission of opening the world through education, offering language, academic, cultural exchange and education travel programs. Some companies are in the business of technology. Others are in the business of finance, sports, or soft drinks. At EF, we’re in a different kind of business. One that’s a little less tangible, and a lot more important. We’re in the business of understanding. For 60 years we’ve been the leader in international educational programs and culturally rich travel experiences with the power to change how people think, feel and act. The programs we deliver open the world to students and travelers in ways that challenge biases, overcome barriers, and pave the way for a more understanding world. You’ll find us working across more than 50 countries, with offices in some of the world’s greatest cities—each one filled with smart, driven people who push each other to be better every day. And yes, we have technology, we have finance, we even have sports with our own professional cycling team. But it’s what we do with it—building greater understanding, breaking down barriers, and creating a better world that makes all the difference. A notice on recruitment scams EF (Education First) accepts job applicant applications, reviews resumes and will contact you directly if there is an interest in your resume. Only submit your resume through our official website, careers.ef.com. We never ask our applicants to pay a fee for any service whatsoever.

The Bluetooth Classic Hands-Free Profile HF role in subsys/bluetooth/host/classic/hfp_hf.c does not release the AT command buffers that are still queued on hf->tx_pending when the RFCOMM DLC goes down. hfp_hf_disconnected() only cancelled the work items and cleared hf->acl, and no other code path ever dequeues those buffers, so each one is permanently lost from the fixed hf_pool (CONFIG_BT_MAX_CONN + 1 buffers, i.e. two in the default configuration). The same function also left BT_HFP_HF_FLAG_CONNECTED set, and hfp_hf_create() wiped the object with memset() as soon as hf->acl was NULL, without checking whether hf->work, hf->slc_work or hf->deferred_work was still pending or running. The remote Audio Gateway peer controls the trigger end to end and needs no application involvement: an unsolicited +BCS: 1 response makes bcs_handle() call bt_hfp_hf_select_codec() and queue an AT+BCS buffer, which cannot be transmitted while BT_HFP_HF_FLAG_RX_ONGOING is set, and an immediately following RFCOMM DISC strands that buffer. Repeating the connect / +BCS / disconnect cycle a couple of times empties hf_pool for good. With the pool exhausted, HFP command sending fails permanently, and because hfp_hf_send_cmd() allocates with K_FOREVER (bt_rfcomm_create_pdu() → bt_conn_create_pdu()) from the Bluetooth RX context — where that timeout is not downgraded to K_NO_WAIT — one further +BCS from the peer parks the Bluetooth RX thread inside net_buf_alloc() with no possible waker, halting all HCI event processing until the device is rebooted. Separately, reusing the HF slot while a work handler was still queued or running allowed memset() to wipe live k_work items out from under the system workqueue, corrupting shared kernel workqueue state. Exploitation requires an established HFP session (for SSP devices L2CAP enforces authentication before the RFCOMM channel is reachable) and a build with CONFIG_BT_HFP_HF enabled.
The user-mode syscall verifier z_vrfy_rtio_cqe_get_mempool_buffer() in subsys/rtio/rtio_syscalls.c validated its two output parameters, buff and buff_len, with K_SYSCALL_MEMORY_READ() rather than K_SYSCALL_MEMORY_WRITE(). Both are pure out-parameters: z_impl_rtio_cqe_get_mempool_buffer() stores the mempool buffer address and its length through them. The distinction is enforced by every architecture validator — arch_buffer_validate() on RISC-V PMP explicitly accepts the global __rom_region/__rodata_region for reads only, and the ARM MPU validators accept P_RO_U_RO and P_RW_U_RO regions for reads only — so a read-validated pointer is not necessarily writable by the calling thread. An unprivileged user-mode thread that has been granted access to an RTIO context (rtio_access_grant()) can invoke the rtio_cqe_get_mempool_buffer() syscall with buff/buff_len pointing at memory it may read but not write, and with a completion-queue entry whose flags field it fully controls (only RTIO_CQE_FLAG_MEMPOOL_BUFFER in flags[7:0] is required; flags[19:8] and flags[31:20] supply the block index and count). The kernel then performs a pointer-sized and a 4-byte store through those addresses while running in supervisor mode. Reaching the store requires CONFIG_USERSPACE together with CONFIG_RTIO_SYS_MEM_BLOCKS, the configuration behind RTIO_DEFINE_WITH_MEMPOOL; without the latter the implementation returns -ENOTSUP and writes nothing. Two outcomes follow. If the target lies in a memory-domain partition declared K_MEM_PARTITION_P_RW_U_RO (privileged read-write, user read-only), the kernel-mode store succeeds and deposits partly attacker-chosen values into memory the memory domain had marked read-only for that thread, bypassing the partition's write protection. If the target lies in globally readable but unwritable memory such as .text/.rodata in flash, the store faults in kernel mode; the fault is delivered to z_fatal_error() and the default k_sys_fatal_error_handler() halts or reboots the device, giving an unprivileged thread a reliable full denial of service. The read-permission check does bound the damage: the address must still be readable by the calling thread, so kernel-private memory cannot be targeted and no confidential data is disclosed. The fix replaces both checks with K_SYSCALL_MEMORY_WRITE(), so a thread lacking write permission is terminated by K_OOPS before the implementation runs; the cqe argument correctly remains read-validated.
IBM Storage TS4500 Library 1.1.1.6 through 1.12.0.3 could allow a remote authenticated attacker to gain unauthorized administrative privileges due to a race condition.
The html_to_markdown expansion module in MISP Modules contains a server-side request forgery (SSRF) vulnerability in its is_safe_url() URL validation function. The BLOCKED_RANGES list used to reject unsafe destination addresses was incomplete, omitting several critical IP address ranges. Specifically, the following ranges were not blocked: 0.0.0.0/8 (unspecified, which routes to loopback on Linux), 100.64.0.0/10 (carrier-grade NAT per RFC 6598), ::/128 (IPv6 unspecified), fc00::/7 (IPv6 Unique Local Addresses), and fe80::/10 (IPv6 link-local). The existing list only covered IPv4 loopback (127.0.0.0/8), RFC 1918 private ranges, IPv4 link-local (169.254.0.0/16), and IPv6 loopback (::1/128). An authenticated user with the ability to create or modify MISP attributes that trigger the html_to_markdown expansion module could supply URLs pointing to these unblocked internal address ranges. Because the module fetches the URL server-side to convert HTML content to Markdown, the request is made from the MISP server's network context. This allows an attacker to probe and read responses from internal services, carrier-grade NAT infrastructure, or link-local endpoints that would otherwise be unreachable from external networks. IPv4-mapped IPv6 forms (e.g., [::ffff:0.0.0.0]) also bypassed the existing checks. The security impact is primarily confidentiality: an attacker can read data served by internal services reachable from the MISP server. The MISP instance itself is not compromised, but it is abused as a proxy to access otherwise restricted network resources.
A weakness has been identified in H3C Magic NX15 V100R017. This affects the function importprofile of the file /api/upload. This manipulation of the argument fileName causes path traversal. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure.
