If the spinlock protection is added\nin virtcrypto_done_task(), openssl benchmark with multiple processes\nworks well.","aliases":["ECHO-d387-f0ae-30e7"],"modified":"2026-04-21T02:27:06.510744562Z","published":"2026-02-18T14:53:33.015Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:10387-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23229.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/49c57c6c108931a914ed94e3c0ddb974008260a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/552475d0b6cece73a52c0fa5faa0ce45e99df74b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8ee8ccfd60bf17cbdab91069d324b5302f4f3a30"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b505047ffc8057555900d2d3a005d033e6967382"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0a0ded3bb7fd45f720faa48449a930153257d3a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c9e594194795c86ca753ad6ed64c2762e9309d0d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d6f0d586808689963e58fd739bed626ff5013b24"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e69a7b0a71b6561b3b6459f1fded8d589f2e8ac2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23229.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23229"},{"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":"0eb69890e86775d178452880ea0d24384c5ccedf"},{"fixed":"552475d0b6cece73a52c0fa5faa0ce45e99df74b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"75cba72ddb788a5b9c7ed2139fbb84383df029eb"},{"fixed":"8ee8ccfd60bf17cbdab91069d324b5302f4f3a30"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ae4747dab2eab95a68bb2f6c7e904bff0424e1b1"},{"fixed":"c9e594194795c86ca753ad6ed64c2762e9309d0d"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c4c54fce9ec54a59a4ca035af13c2823c76684cc"},{"fixed":"d6f0d586808689963e58fd739bed626ff5013b24"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"fed93fb62e05c38152b0fc1dc9609639e63eed76"},{"fixed":"c0a0ded3bb7fd45f720faa48449a930153257d3a"},{"fixed":"e69a7b0a71b6561b3b6459f1fded8d589f2e8ac2"},{"fixed":"49c57c6c108931a914ed94e3c0ddb974008260a3"},{"fixed":"b505047ffc8057555900d2d3a005d033e6967382"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"96be18c8fff9d57e29621386e2fa17268383ea27"},{"last_affected":"830a4f073f7edd2cc4f30ba95bdc3495d97c2550"},{"last_affected":"8862c0d2e47ba1733d9687fe0ff4e02d6e391255"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23229.json"}}],"schema_version":"1.7.5"}
