CVE-2025-39689

CVE-2025-39689 affects the Linux kernel’s ftrace filter handling. The issue arose because readers (set_ftrace_filter/set_ftrace_notrace) kept a pointer to the global tracer hash, unlike writers who copy the hash. The pointer could remain static across calls that release locks and update the globa...
