{"id":"CVE-2026-80992","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80992","summary":"net: ravb: avoid dereferencing an invalid PTP clock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ravb: avoid dereferencing an invalid PTP clock\n\nThe PTP clock is unavailable before the first open, so querying its\nindex can dereference a NULL pointer. Registration failures can also\nleave an error pointer in priv->ptp.clock.\n\nCache the PHC index separately and report -1 while no clock is\nregistered. Normalize registration errors to NULL and preserve the\nstatic timestamping capabilities.","published":"2026-09-11T19:42:48.855Z","modified":"2026-09-14T03:45:51.141766759Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.109"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0aaa53936419cf0c19c670387fc6d431e042a1b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f77af0aaf277413ff32f6ff8c2c4282bd64c897"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8d4d06d6e2b501cb8e30ed3b1924c470358e8052"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fc710f89a644e030a7ca15343176ca862fd61b9d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80992.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80992"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T03:45:51.141766759Z"}}
