CVE-2026-12365 Use-after-free in Zephyr delayable work-queue cancellation under SMP timing race

A use-after-free exists in the Zephyr second-generation work queue kernel/work.c in the handling of delayable work timeouts. When a delayable work item's timeout has been dequeued and its handler worktimeout is in flight blocked acquiring the work-queue spinlock, a concurrent cancellation does no...

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...

The vulnerability of the smp_cmdPairingReq() function in the net/bluetooth/smp.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

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...
