{"id":"CVE-2026-72241","summary":"leds: uleds: Fix potential buffer overread","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nleds: uleds: Fix potential buffer overread\n\nThe name string supplied by userspace is not guaranteed to be\nnull-terminated, so using strchr() on it might result in a buffer\noverread. The same thing will happen when said string is used by\nthe LED class device.\n\nFix this by using strnchr() instead and explicitly check that\nthe name string is properly null-terminated.","modified":"2026-08-18T03:31:00.554602514Z","published":"2026-08-15T05:54:29.640Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72241.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/263ccdd627caeda6e980ed3c6e32bb4fd6b380b1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ad6f6c9209e5777b896def9876708853ae26d0d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5bb89e23729f3a59592d699a437bb001f24b8f67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6dd51d84a9502553e58beade72823258871b8111"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8bf529571cca60fb8af65d6d034bdbbc99a9127c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a84c59121dfdc7b324f72dc5012aa8fe5e7d2d7b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a91ac9fdac7385cbc98aeae55b4e5302125497a2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c19fe864f667afc49d1391d764e20b66555bcf7a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72241.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72241"},{"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":"e381322b0190c1253d347de3f28b5c37756fb651"},{"fixed":"a84c59121dfdc7b324f72dc5012aa8fe5e7d2d7b"},{"fixed":"5bb89e23729f3a59592d699a437bb001f24b8f67"},{"fixed":"5ad6f6c9209e5777b896def9876708853ae26d0d"},{"fixed":"8bf529571cca60fb8af65d6d034bdbbc99a9127c"},{"fixed":"a91ac9fdac7385cbc98aeae55b4e5302125497a2"},{"fixed":"6dd51d84a9502553e58beade72823258871b8111"},{"fixed":"263ccdd627caeda6e980ed3c6e32bb4fd6b380b1"},{"fixed":"c19fe864f667afc49d1391d764e20b66555bcf7a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72241.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72241.json"}}],"schema_version":"1.9.0"}
