"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: fix metabuf leak in inode xattr initialization\n\ncommit bb88e8da0025 (\"erofs: use meta buffers for xattr operations\")\nconverted xattr operations to use on-stack erofs_buf instances.\nerofs_init_inode_xattrs() uses such a metabuf while reading the inline\nxattr header and shared xattr id array.\n\nSome error paths after erofs_read_metabuf() leave through out_unlock\nwithout dropping the metabuf, so the folio reference can leak.\n\nConsolidate the cleanup at out_unlock. erofs_put_metabuf() is a\nno-op if no folio has been acquired, and this keeps all paths after\ntaking EROFS_I_BL_XATTR_BIT covered by a single cleanup site."
