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":"2026-10-23T17:13:16.161+00:00","modifiedAt":"2026-10-23T17:13:16.161+00:00","affected":[{"ecosystem":"Vendor product","name":"tokio","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tokio-rs\",\n                    \"product\": \"tokio\",\n                    \"versions\": [\n                        {\n                            \"version\": \"= 1.54.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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","score":5.8,"severity":"MEDIUM"}],"references":["https://github.com/tokio-rs/tokio/security/advisories/GHSA-5wjr-9356-4wc8","https://github.com/tokio-rs/tokio/pull/8458","https://github.com/tokio-rs/tokio/pull/8692","https://github.com/tokio-rs/tokio/commit/2b4eba7833864c04ecd2f3e5f4a97ff4f6fa28d0","https://github.com/tokio-rs/tokio/commit/5ed619bbaba87357ee5103d71b75e7c84cad99c9","https://github.com/tokio-rs/tokio/releases/tag/tokio-1.54.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115567","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115567","identifiers":["CVE-2026-115567"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
