CVE-2025-68329 tracing: Fix WARN_ON in tracing_buffers_mmap_close for split VMAs

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...

CVE-2025-68186

The CVE covers a Linux kernel issue in the ring-buffer code. The vulnerability stems from ring_buffer_map_get_reader() being too strict: when the reader catches up to the writer and there is still data on the reader page, rb_get_reader_page() can return NULL and trigger a warning. The fix ensures...
