CVE-2026-97950

A flaw was found in the Linux kernel's configfs filesystem. A local user could exploit a race condition between creating a symbolic link and deleting its target directory to cause a Denial of Service DoS. When this race condition occurs, the kernel attempts to access a freed directory entry, whic...

CVE-2026-97949

A flaw was found in the Linux kernel's configfs filesystem. A race condition between directory removal and symbolic link creation can result in a use-after-free vulnerability, where the system attempts to access memory after it has been released. A local user can exploit this flaw by concurrently...

CVE-2026-97950

The Linux kernel contains a vulnerability in configfs where create_link() incorrectly relies on an item reference that pins the item but not its dentry. A race condition between a symlink creation and an rmdir of its target can cause configfs_remove_dir() to release the dentry via simple_rmdir() ...
