  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: delimit inode_share cache key components\n\nPreviously, inode_share keys were encoded as follows:\n\n  fingerprint || domain_id\n\nIt would be better to have a separator between the fingerprint and domain\nID so that the fingerprint won't be parsed as part of a domain ID.\n\nChange the key encoding as follows:\n\n  domain_id || '\\0' || fingerprint\n\nSince domain_id is a NUL-terminated string, this makes the in-memory key\nindices unambiguous.",
