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-2026-11742 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-2026-64501

A flaw was found in the Linux kernel's adsigmadelta driver for analog-to-digital converters ADCs. This vulnerability occurs when the Chip Select CS line, which controls communication with the ADC, remains asserted after a conversion or in an error state. This can prevent other devices on the Seri...

CVE-2026-64435

A flaw was found in the Linux kernel's auditing subsystem. Multiple readers could access the auditqueue length qlen concurrently with a writer without proper synchronization, leading to a data race. This race condition could result in inconsistent data reads, potentially causing unpredictable...
