A vulnerability has been found that makes it possible to disclose portions of the TKey’s data in RAM over the USB interface. To exploit the vulnerability an attacker needs to use a custom client application and to touch the TKey. No secret is disclosed. All client applications integrating tkey-device-signer should upgrade to version 1.0.0 to receive a fix. No known workarounds are available.","publishedAt":"2024-04-23T17:38:09.614Z","updatedAt":"2024-08-02T02:13:39.266Z","severity":{"score":2.2,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["tillitis tkey-device-signer"],"affected":[{"vendor":"tillitis","product":"tkey-device-signer","versions":[{"version":"< 1.0.0","status":"affected"}]}],"references":["https://github.com/tillitis/tkey-device-signer/security/advisories/GHSA-frqc-62hv-379p","https://bugbounty.tillitis.se/security-bulletins/tillitis-security-bulletin-240115-1"],"weaknesses":["CWE-125","CWE-367"],"ingestedAt":"2026-10-29T20:07:21.467Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/32xxx/CVE-2024-32482.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-32482","state":"PUBLISHED","datePublished":"2024-04-23T17:38:09.614Z","dateUpdated":"2024-08-02T02:13:39.266Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-04-12T19:41:51.168Z"},"containers":{"cna":{"title":"Tillitis TKey Signer possible RAM disclosure vulnerability","descriptions":[{"lang":"en","value":"The Tillitis TKey signer device application is an ed25519 signing tool.
