A control-flow timing lean has been identified in the reference implementation of the Kyber key encapsulation mechanism when it is compiled with Clang 15-18 for `-Os`, `-O1`, and other compilation options. A proof-of-concept local attack on the reference implementation leaks the entire ML-KEM 512 secret key in ~10 minutes using end-to-end decapsulation timing measurements. The issue has been fixed in version 0.10.1. As a possible workaround, some compiler options may produce vectorized code that does not leak secret information, however relying on these compiler options as a workaround may not be reliable."}],"source":{"advisory":"GHSA-f2v9-5498-2vpp","discovery":"UNKNOWN"}},"adp":[{"affected":[{"vendor":"open_quantum_safe","product":"liboqs","cpes":["cpe:2.3:a:open_quantum_safe:liboqs:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.10.0","versionType":"custom"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-06-10T18:07:52.893861Z","id":"CVE-2024-36405","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-10T18:09:22.295Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T03:37:05.189Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/open-quantum-safe/liboqs/security/advisories/GHSA-f2v9-5498-2vpp","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/open-quantum-safe/liboqs/security/advisories/GHSA-f2v9-5498-2vpp"},{"name":"https://github.com/open-quantum-safe/liboqs/commit/982c762c242ef549c914891b47bf6e0ed6321f91","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/open-quantum-safe/liboqs/commit/982c762c242ef549c914891b47bf6e0ed6321f91"},{"name":"https://github.com/pq-crystals/kyber/commit/9b8d30698a3e7449aeb34e62339d4176f11e3c6c","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/pq-crystals/kyber/commit/9b8d30698a3e7449aeb34e62339d4176f11e3c6c"},{"name":"https://github.com/open-quantum-safe/liboqs/blob/7eecda6095c003ddded7175a1ffdf35a2ce63ed5/src/kem/kyber/pqcrystals-kyber_kyber512_ref/poly.c#L166","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/open-quantum-safe/liboqs/blob/7eecda6095c003ddded7175a1ffdf35a2ce63ed5/src/kem/kyber/pqcrystals-kyber_kyber512_ref/poly.c#L166"}]}]}}
