CVE-2025-38564

CVE-2025-38564 involves the Linux kernel perf subsystem. The issue occurs in perf_mmap() when mapping a buffer read‑only into the page table after the buffer is allocated or attached. If map_range() fails, the kernel currently zaps the page table entries but does not invoke perf_mmap_close(), lea...
