This creates an\ninconsistent state where ni->attr_list.size is zero, but ni->attr_list.le is\nnon-null. This causes ni_enum_attr_ex to incorrectly assume that no attribute\nlist exists and enumerates only the primary MFT record. When it finds\nATTR_LIST, the code reloads it and restarts the enumeration, repeating\nindefinitely. The mount operation never completes, hanging the kernel thread.\n\nThis patch adds validation to ensure that data_size is non-zero before memory\nallocation. When a zero-sized ATTR_LIST is detected, the function returns\n-EINVAL, preventing a DoS vulnerability." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected",
