CVE-2024-47733

Kernel warning via incomplete netfs subtree removal

Published Oct 21, 2024 · Updated May 11, 2026

Resource cleanup error in affected Linux kernel branches allows local users to trigger a warning by unloading the netfs module. netfs_exit() calls remove_proc_entry() on fs/netfs while its requests child remains, leaking the nonempty procfs subtree instead of deleting it recursively. Reaching the flaw requires permission to unload the module; published evidence demonstrates leaked procfs entries and a warning that becomes a kernel panic when panic_on_warn is enabled.
