{"id":"CVE-2026-63860","summary":"RDMA/core: Prefer NLA_NUL_STRING","details":"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.","modified":"2026-07-22T03:32:04.769831627Z","published":"2026-07-19T14:04:48.153Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63860.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/137b5918931d4d05aa8ea8d3adf67f7224eef63c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5877c043398d5fa0e93919a3d837e5cd7a98a961"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ed3d14fc45d3da6025e7fe4a6a09066856698e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/87111356d58d86edb221ba144d261ed83a5b8bbe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/abda65bdd13084c771842adaac1f652d0660dd82"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c26a0052cceed4c4d380ee5808b699f937fb58d8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2c7b39dde2e61df8157066969cc2a408cd3dcd9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fcd07d3b8ee7a39b344d73aed69c1a68cd9eacdf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63860.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63860"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"30dc5e63d6a5ad24894b5512d10b228d73645a44"},{"fixed":"fcd07d3b8ee7a39b344d73aed69c1a68cd9eacdf"},{"fixed":"87111356d58d86edb221ba144d261ed83a5b8bbe"},{"fixed":"abda65bdd13084c771842adaac1f652d0660dd82"},{"fixed":"137b5918931d4d05aa8ea8d3adf67f7224eef63c"},{"fixed":"5877c043398d5fa0e93919a3d837e5cd7a98a961"},{"fixed":"f2c7b39dde2e61df8157066969cc2a408cd3dcd9"},{"fixed":"c26a0052cceed4c4d380ee5808b699f937fb58d8"},{"fixed":"6ed3d14fc45d3da6025e7fe4a6a09066856698e2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-63860.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.16.0"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-63860.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
