CVE-2025-38563

CVE-2025-38563 affects the Linux kernel perf subsystem. The issue arises when perf mmap-based mappings can be split (VMA split) after initial mapping, causing mismatched offsets/sizes and leaking reference counts for ringbuffer/auxiliary buffers. The fix adds vm_operations_struct.may_split() and ...
