  "details": "In the Linux kernel, the following vulnerability has been resolved:  erofs: fix metabuf leak in inode xattr initialization  commit bb88e8da0025 (\"erofs: use meta buffers for xattr operations\") converted xattr operations to use on-stack erofs_buf instances. erofs_init_inode_xattrs() uses such a metabuf while reading the inline xattr header and shared xattr id array.  Some error paths after erofs_read_metabuf() leave through out_unlock without dropping the metabuf, so the folio reference can leak.  Consolidate the cleanup at out_unlock. erofs_put_metabuf() is a no-op if no folio has been acquired, and this keeps all paths after taking EROFS_I_BL_XATTR_BIT covered by a single cleanup site.",
