CVE-2026-68323

A race condition was found in the Linux kernel TIPC UDP bearer replication list handling (tipc_udp_rcast_add and cleanup_bearer). Without proper serialization, updates to ub->rcast.list can corrupt the list, potentially triggering a kernel bug and denial of service. The fix adds a spinlock to ...

CVE-2026-68138

The CVE-2026-68138 issue concerns a race in the Linux kernel networking scheduler (net/sched) where qdisc_rtab_list and a non-atomic refcnt are mutated without proper locking. The historical RTNL mutex was supposed to serialize rate-table lookups, inserts, and frees, but CLS_FLOWER/TCF_PROTO_OPS_...

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-2026-11742

CVE-2026-11742 describes a use-after-free race in Zephyr’s kernel queue helpers: z_queue_node_peek() can dereference a node after another thread preempts or unlinks it via k_queue_get(), because peek operations weren’t protected by the queue spinlock. A concurrent consumer may free the node and i...

CVE-2026-64429

A flaw was found in the Linux kernel. The Spreadtrum EIC External Interrupt Controller driver incorrectly uses a standard spinlock in a critical interrupt handling path. When running on a PREEMPTRT Preemptible Real-Time kernel, this can cause the system to attempt to sleep in an invalid context...

CVE-2026-64292

A flaw was found in the Linux kernel's iommufd component. A local user can exploit this vulnerability by allocating large veventq queues, which are processed inside a spinlock. This can lead to the exhaustion of atomic memory reserves, resulting in a Denial of Service DoS condition...
