Prefer NLA_NUL_STRING","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/core: Prefer NLA_NUL_STRING\n\nThese attributes are evaluated as c-string (passed to strcmp), but\nNLA_STRING doesn't check for the presence of a \\0 terminator.\n\nEither this needs to switch to nla_strcmp() and needs to adjust printf fmt\nspecifier to not use plain %s, or this needs to use NLA_NUL_STRING.\n\nAs the code has been this way for long time, it seems to me that userspace\ndoes include the terminating nul, even tough its not enforced so far, and\nthus NLA_NUL_STRING use is the simpler solution.","state":0,"publishedAt":"2026-07-19T14:04:48.153+00:00","modifiedAt":"2026-10-19T20:07:52.376+00:00","affected":[{"ecosystem":"Vendor
