What is CVE-2025-37876?

A flaw within the Linux kernel's memory management implementation can lead to system crashes under specific configuration settings. When CONFIG_NETFS_SUPPORTS is enabled while CONFIG_PROC_FS is disabled, attempts to allocate memory through the netfs functionality can trigger critical errors, causing the system to fail. The issue stems from an improper setup within netfs_init(), where the /proc/fs/netfs directory is prematurely created without necessary configurations, leading to memory allocation failures. This vulnerability needs to be addressed to prevent potential instability in systems relying on the netfs feature.
