CVE-2026-74343

CVE-2026-74343 describes a Linux kernel kernfs xattr race: multiple inodes across different superblocks can share kernfs_node->iattr->xattrs, and VFS per-inode locks are not enough to serialize concurrent xattr modifications. The fix introduces per-node hashing mutexes (renaming open_file_m...
