CVE-2026-89747

CVE-2026-89747 is a use-after-free vulnerability in the Linux kernel tracing subsystem , specifically in the trace_pipe read path. Writing to buffer_subbuf_size_kb triggers ring_buffer_subbuf_order_set(), which frees all sub-buffers (including the reader page) while active trace_pipe readers stil...
