CVE-2025-21999

Summary: CVE-2025-21999 affects the Linux kernel’s procfs inode creation path. A use-after-free (UAF) can occur when a module is freed (rmmod) while a /proc entry’s inode is instantiated, due to dereferencing pde->proc_ops that belongs to the module, after proc entry registration. The root cau...
