CVE-2026-19293

The vulnerability CVE-2026-19293 concerns the BLE SMP (Security Manager Protocol) security request where the peripheral omits the maximum supported encryption key size. This omission can allow brute-forcing of the key more easily for an adjacent attacker. The entry cites the BLERP paper and provi...

Linux Bluetooth SMP smp_cmdPairingReq Buffer Overflow

The vulnerability of the smpcmdPairingReq function in the net/bluetooth/smp.c module of the Linux operating system is related to insufficient security checks for protected connections. Exploiting this vulnerability could allow a remote attacker to compromise the confidentiality, integrity, and...

CVE-2026-11742 Use-after-free race in kernel `k_queue_peek_head/tail` due to missing spinlock

The kernel queue helper zqueuenodepeek in kernel/queue.c dereferences a node taken from a queue's dataq list, reading the node's flag byte and, for items enqueued via kqueueallocappend/allocprepend, the data pointer of an internally allocated allocnode struct. The implementations of...

CVE-2026-10681 SMP race in `thread_idx_alloc()` lets concurrent `k_object_alloc(K_OBJ_THREAD)` callers share a kernel-object permission slot

In Zephyr's userspace dynamic-objects subsystem, threadidxalloc in kernel/userspace/userspace.c allocated a new thread permission index from the global threadidxmap bitmap without holding listslock. On SMP systems, two user-mode threads invoking the kobjectallocKOBJTHREAD syscall concurrently can...

CVE-2026-10681

CVE-2026-10681 overview (Zephyr) : In the userspace dynamic-objects subsystem, thread_idx_alloc() reads and clears the global _thread_idx_map[] bitmap without holding lists_lock. On SMP systems, concurrent k_object_alloc(K_OBJ_THREAD) calls can observe the same free bit, perform a non-atomic RMW,...

SUSE CVE-2026-64248

In the Linux kernel, the following vulnerability has been resolved: MIPS: smp: report dying CPU to RCU in stopthiscpu smpsendstop parks all secondary CPUs in stopthiscpu. The function marks the CPU offline for the scheduler via setcpuonlinefalse but never informs RCU, so RCU keeps expecting a...

CVE-2026-10681: Concurrent Execution using Shared Resource with Improper Synchronization

In Zephyr's userspace dynamic-objects subsystem, threadidxalloc in kernel/userspace/userspace.c allocated a new thread permission index from the global threadidxmap bitmap without holding listslock. On SMP systems, two user-mode threads invoking the kobjectallocKOBJTHREAD syscall concurrently can...

CVE-2026-64250

The CVE-2026-64250 entry pertains to the Linux kernel on LoongArch. The root cause is that smp_send_stop() parks secondary CPUs and marks the offline CPU for the scheduler without informing RCU, causing RCU to wait for a quiescent state from CPUs that are spinning with interrupts disabled. The is...
