{"id":"CVE-2026-43138","summary":"reset: gpio: suppress bind attributes in sysfs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nreset: gpio: suppress bind attributes in sysfs\n\nThis is a special device that's created dynamically and is supposed to\nstay in memory forever. We also currently don't have a devlink between\nit and the actual reset consumer. Suppress sysfs bind attributes so that\nuser-space can't unbind the device because - as of now - it will cause a\nuse-after-free splat from any user that puts the reset control handle.","modified":"2026-07-08T08:13:28.643596578Z","published":"2026-05-06T11:27:24.232Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43138.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09d6efc6abd42809956d598906c222ccd1c8ae92"},{"type":"WEB","url":"https://git.kernel.org/stable/c/16de4c6a8fe9ff497ca1aba33ef0dbee09f11952"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d7d869f074f98c34fe23f6a56e5f3acc1f95a2b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/76801c3dfca0ac6339a23e9615b5f23e25b8644c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43138.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43138"},{"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":"cee544a40e4426040946e685988b1489f13e6600"},{"fixed":"09d6efc6abd42809956d598906c222ccd1c8ae92"},{"fixed":"76801c3dfca0ac6339a23e9615b5f23e25b8644c"},{"fixed":"1d7d869f074f98c34fe23f6a56e5f3acc1f95a2b"},{"fixed":"16de4c6a8fe9ff497ca1aba33ef0dbee09f11952"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43138.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43138.json"}}],"schema_version":"1.7.5"}
