{"id":"CVE-2026-93155","summary":"crypto: keembay - Fix AEAD unregister count in error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: keembay - Fix AEAD unregister count in error path\n\nregister_aes_algs() registers the AEAD algorithms before registering the\nskcipher algorithms.  If skcipher registration fails, the function unwinds\nthe earlier AEAD registration with crypto_engine_unregister_aeads(), but it\npasses ARRAY_SIZE(algs), which is the skcipher table size.\n\nUse ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper\niterates over the same table that was registered.  Also clarify the nearby\ncomment: the crypto registration helpers clean up algorithms registered\nwithin the same call, while this function must still unwind earlier\nsuccessful registration steps.","modified":"2026-09-19T03:47:26.928571975Z","published":"2026-09-17T16:11:50.792Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93155.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/27ec91c29ee155cc507b2f56221fc6fab65dbb51"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5607b101d86cbee8dd1ffab784495c880ca73383"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5bbb726d27ff6dff750264e51aa665538394d0f8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3217fe7998622728a53dff405615e0971949eaf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e264401ce4776a288524e5b87593d4d864147115"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93155.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93155"},{"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":"88574332451380f4b51f6ca88ab9810e714bfb9b"},{"fixed":"27ec91c29ee155cc507b2f56221fc6fab65dbb51"},{"fixed":"5607b101d86cbee8dd1ffab784495c880ca73383"},{"fixed":"5bbb726d27ff6dff750264e51aa665538394d0f8"},{"fixed":"a3217fe7998622728a53dff405615e0971949eaf"},{"fixed":"e264401ce4776a288524e5b87593d4d864147115"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93155.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"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-2026-93155.json"}}],"schema_version":"1.9.0"}
