{"id":"CVE-2026-93160","summary":"crypto: atmel-ecc - reject hardware ECDH without a public key","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: atmel-ecc - reject hardware ECDH without a public key\n\nThe hardware ECDH path in atmel_ecdh_compute_shared_secret() uses the\nprivate key stored in the device. However, the public key is cached only\nafter atmel_ecdh_set_secret() successfully generated that private key\nfor the current tfm.\n\natmel_ecdh_generate_public_key() already rejects requests when no public\nkey is cached. Add the same check to atmel_ecdh_compute_shared_secret()\nto prevent the device from using a private key that was not generated\nfor the current tfm.","modified":"2026-09-19T03:47:22.777800423Z","published":"2026-09-17T16:11:54.517Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93160.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2b40bab362d2b598f34e5ccd4694cedc3c2553d4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/33241f198287960bba5fc2251400896762650bfa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ea8b780d68f02fe235c5051ce8ac4b4940b9259"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e33791dfcc6459e402a524669093cd953d5b2df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6457162f74f45284ade2da644a4f0c54758ac0a6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/add28e9988902d29ea93f4869280b4a16a049ea5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e64d6f1aae8c837cb3f0446bf44108226d7370f4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f240f9b588f4e2de89822adebf560a96b5d263ed"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93160.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93160"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"11105693fa05f499532b330da65c78ff93ed4440"},{"fixed":"5e33791dfcc6459e402a524669093cd953d5b2df"},{"fixed":"33241f198287960bba5fc2251400896762650bfa"},{"fixed":"3ea8b780d68f02fe235c5051ce8ac4b4940b9259"},{"fixed":"6457162f74f45284ade2da644a4f0c54758ac0a6"},{"fixed":"2b40bab362d2b598f34e5ccd4694cedc3c2553d4"},{"fixed":"e64d6f1aae8c837cb3f0446bf44108226d7370f4"},{"fixed":"add28e9988902d29ea93f4869280b4a16a049ea5"},{"fixed":"f240f9b588f4e2de89822adebf560a96b5d263ed"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93160.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93160.json"}}],"schema_version":"1.9.0"}
