CVE-2026-23101

The CVE-2026-23101 issue affects the Linux kernel LED subsystem. The root cause is a race where an LED was added to leds_list before led_init_core() and before led_classdev.set_brightness_work is initialized. This could allow a default-trigger LED to call led_trigger_set() and queue an uninitiali...

CVE-2026-23074

CVE-2026-23074 is a Linux kernel vulnerability in net/sched teql where the teql queuing discipline may be used outside its intended root qdisc, allowing a crafted packet sequence to create a use-after-free scenario in the qfq/qos path due to queue length (qlen) handling. The root cause is that te...

CVE-2026-23074 net/sched: Enforce that teql can only be used as root qdisc

In the Linux kernel, the following vulnerability has been resolved: net/sched: Enforce that teql can only be used as root qdisc Design intent of teql is that it is only supposed to be used as root qdisc. We need to check for that constraint. Although not important, I will describe the scenario th...

CVE-2026-23069

CVE-2026-23069 (Linux kernel) : In vsock/virtio, the credit calculation in virtio_transport_get_credit() can underflow when the peer’s advertised buffer (peer_buf_alloc) shrinks while data is in flight, potentially allowing more data to be queued than the peer can handle. The issue arises from un...

CVE-2026-23066

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix recvmsg unconditional requeue If rxrpcrecvmsg fails because MSGDONTWAIT was specified but the call at the front of the recvmsg queue already has its mutex locked, it requeues the call - whether or not the call is alrea...

CVE-2026-23066 rxrpc: Fix recvmsg() unconditional requeue

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix recvmsg unconditional requeue If rxrpcrecvmsg fails because MSGDONTWAIT was specified but the call at the front of the recvmsg queue already has its mutex locked, it requeues the call - whether or not the call is alrea...

CVE-2026-23066

CVE-2026-23066 concerns the Linux kernel RXRPC receive path. The issue arises in rxrpc_recvmsg() where, if MSG_DONTWAIT is requested and the front of the recvmsg queue has its mutex held, the call is unconditionally requeued, potentially corrupting the recvmsg queue and causing Use-After-Frees or...

CVE-2026-23063

CVE-2026-23063 pertains to the Linux kernel, specifically the UACCE accelerator framework. The issue arises in the queue release path for uacce_queue when resources could be freed concurrently (e.g., during poweroff -f with accelerators still active). The root cause is unsafe sequencing of operat...
