Use tty_port_tty_get()/tty_kref_put() to hold a proper reference\nfor the duration the tty pointer is needed.","published":"2026-08-22T15:32:44.493Z","modified":"2026-08-24T11:47:18.222939300Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.265"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/38400673c9bfb39cfc87539e1a072087e98f4e4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/38a0aa593ebc275aea6f79534d07f44e43768ce6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3f6b1d3fcfc26dc3fc85262f753439df93b055b4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b664592e9ba8c47c9e23408db7ba52eb9f946c8a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b84fd400f80adf4d1c88fbce50ae1cf2f8119e65"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cab5a342f0589334046741006d8a280514f94235"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc4a1a2ce0c58eafd477effb055863935260ddc1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e25d47a526939ad44b75f778b8a7500562b84fc1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74675.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74675"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-24T11:47:18.222939300Z"}}
