  "details": "In the Linux kernel, the following vulnerability has been resolved:  dm era: fix NULL pointer dereference in metadata_open()  metadata_open() returns NULL when kzalloc_obj() fails, but the caller era_ctr() only checks IS_ERR(md).  Since IS_ERR(NULL) returns false, the NULL pointer is treated as a valid result and later assigned to era-\u003emd, leading to a NULL pointer dereference when the metadata is accessed.  Fix this by returning ERR_PTR(-ENOMEM) on allocation failure, consistent with dm-cache-metadata.c, dm-thin-metadata.c, and dm-clone-metadata.c which all use ERR_PTR(-ENOMEM) for the same pattern.",
