CVE-2025-39813

CVE-2025-39813 concerns the Linux kernel ftrace subsystem. A race between ftrace_dump() and trace_pipe reads could trigger WARN_ON_ONCE in trace_printk_seq() when trace data is consumed by other readers, causing iter.seq to be mispopulated. The documented fix moves the trace_printk_seq() call ins...
