{"id":"CVE-2025-68819","summary":"media: dvb-usb: dtv5100: fix out-of-bounds in dtv5100_i2c_msg()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: dvb-usb: dtv5100: fix out-of-bounds in dtv5100_i2c_msg()\n\nrlen value is a user-controlled value, but dtv5100_i2c_msg() does not\ncheck the size of the rlen value. Therefore, if it is set to a value\nlarger than sizeof(st-\u003edata), an out-of-bounds vuln occurs for st-\u003edata.\n\nTherefore, we need to add proper range checking to prevent this vuln.","modified":"2026-04-02T13:03:52.548529Z","published":"2026-01-13T15:29:22.695Z","related":["MGASA-2026-0017","MGASA-2026-0018","SUSE-SU-2026:0447-1","SUSE-SU-2026:0471-1","SUSE-SU-2026:0472-1","SUSE-SU-2026:0587-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","openSUSE-SU-2026:20287-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68819.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4a54d8fcb093761e4c56eb211cf4e39bf8401fa1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/61f214a878e96e2a8750bf96a98f78c658dba60c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac92151ff2494130d9fc686055d6bbb9743a673e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b91e6aafe8d356086cc621bc03e35ba2299e4788"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2305b4c5fc15e20ac06c35738e0578eb4323750"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2c293ea7b61f12cdaad1e99a5b4efc58c88960a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe3e129ab49806aaaa3f22067ebc75c2dfbe4658"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68819.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68819"},{"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":"60688d5e6e6e2ae62f29762d1e3b2aec2dbd3817"},{"fixed":"c2c293ea7b61f12cdaad1e99a5b4efc58c88960a"},{"fixed":"c2305b4c5fc15e20ac06c35738e0578eb4323750"},{"fixed":"61f214a878e96e2a8750bf96a98f78c658dba60c"},{"fixed":"4a54d8fcb093761e4c56eb211cf4e39bf8401fa1"},{"fixed":"fe3e129ab49806aaaa3f22067ebc75c2dfbe4658"},{"fixed":"ac92151ff2494130d9fc686055d6bbb9743a673e"},{"fixed":"b91e6aafe8d356086cc621bc03e35ba2299e4788"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68819.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.28"},{"fixed":"5.10.248"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.198"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.120"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68819.json"}}],"schema_version":"1.7.5"}
