CVE-2026-89747

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix use-after-free in tracepipe read on sub-buffer order change Writing to buffersubbufsizekb calls ringbuffersubbuforderset, which frees every sub-buffer of the ring buffer, including the reader page, and replaces them...

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...
