{"schemaVersion":3,"id":"CVE-2026-21864","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Valkey-Bloom is a Rust based Valkey module which brings a Bloom Filter (Module) data type into the Valkey distributed key-value database. Prior to commit a68614b6e3845777d383b3a513cedcc08b3b7ccd, a specially crafted `RESTORE` command can cause Valkey to hit an assertion, causes the server to shutdown. Valkey modules are required to handle errors in RDB parsing by using `VALKEYMODULE_OPTIONS_HANDLE_IO_ERRORS` flag. If this flag is not set, errors encountered during parsing result in a system assertion which shuts down the system. Even though the Valkey-bloom module correctly handled the parsing, it did not originally set the flag. Commit a68614b6e3845777d383b3a513cedcc08b3b7ccd contains a patch. One may mitigate this defect by disabling the `RESTORE` command if it is unused by one's application.","dates":{"published":"2026-02-24T00:24:15.677Z","modified":"2026-02-26T14:38:37.387Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00273,"percentile":0.18487,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.016,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00257},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00273,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00273,"percentile":0.18487}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00257,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00267,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","sc
