PatchTheCVECVE-2026-11742: The kernel queue helper z_queue_node_peek() in kernel/queue.c dereferences a node taken from a queue's data_q
CVE-2026-11742 is a low-severity flaw (CVSS 3.6) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The kernel queue helper z_queue_node_peek() in kernel/queue.c dereferences a node taken from a queue's data_q list, reading the node's flag byte and, for items enqueued via k_queue_alloc_append/alloc_prepend, the data pointer of an internally allocated alloc_node struct. The implementations of z_impl_k_queue_peek_head() and z_impl_k_queue_peek_tail() performed this read-and-dereference without holding the queue's spinlock, while every other acces
