CVE-2026-23294

A flaw was found in the Linux kernel. A race condition in the devmap component, specifically within the xdpdevbulkqueue bq on PREEMPTRT kernels, allows multiple preemptible tasks on the same CPU to concurrently access the bq. This can lead to a use-after-free vulnerability, potentially resulting ...

CVE-2026-23374

CVE-2026-23374 affects the Linux kernel blktrace path. The root cause is tracing_record_cmdline() using __this_cpu_read()/__this_cpu_write() on a per-CPU variable while preemption is enabled, which is unsafe and triggers a kernel BUG in preemptible code through __blk_add_trace() paths. Public wri...

CVE-2026-23342

CVE-2026-23342 describes a race in the Linux kernel’s PREEMPT_RT path for BPF cpumap/xdp_bulk_queue. The issue arises when bq_enqueue() and __cpu_map_flush() run concurrently on the same CPU, breaking assumptions about atomicity and enabling races such as double __list_del_clearprev() and concurr...
