In 1.54.0, a race condition between tokio::time::Interval::poll_tick (including .tick().await) and the multi-threaded runtime's time driver could drop an internal timer entry without synchronizing with the driver thread that was firing it. The race caused a use-after-free on the timer's waker and task state in safe Rust, which could produce assertion panics, task reference-count corruption, or heap memory corruption. This issue is fixed in 1.54.1.","state":0,"publishedAt":"2026-10-23T18:17:21.303+00:00","modifiedAt":"2026-10-23T19:42:24.553+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.8,"severity":"MEDIUM"}],"references":["https://github.com/tokio-rs/tokio/commit/2b4eba7833864c04ecd2f3e5f4a97ff4f6fa28d0","https://github.com/tokio-rs/tokio/commit/5ed619bbaba87357ee5103d71b75e7c84cad99c9","https://github.com/tokio-rs/tokio/pull/8458","https://github.com/tokio-rs/tokio/pull/8692","https://github.com/tokio-rs/tokio/releases/tag/tokio-1.54.1","https://github.com/tokio-rs/tokio/security/advisories/GHSA-5wjr-9356-4wc8"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-115567","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-362"],"productCriteria":[],"sourceDates":{"published":"2026-10-23T18:17:21.303","lastModified":"2026-10-23T19:42:24.553"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
