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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/crypto/intel/keembay/keembay-ocs-aes-core.c"],"versions":[{"version":"88574332451380f4b51f6ca88ab9810e714bfb9b","lessThan":"27ec91c29ee155cc507b2f56221fc6fab65dbb51","status":"affected","versionType":"git"},{"version":"88574332451380f4b51f6ca88ab9810e714bfb9b","lessThan":"5607b101d86cbee8dd1ffab784495c880ca73383","status":"affected","versionType":"git"},{"version":"88574332451380f4b51f6ca88ab9810e714bfb9b","lessThan":"5bbb726d27ff6dff750264e51aa665538394d0f8","status":"affected","versionType":"git"},{"version":"88574332451380f4b51f6ca88ab9810e714bfb9b","lessThan":"a3217fe7998622728a53dff405615e0971949eaf","status":"affected","versionType":"git"},{"version":"88574332451380f4b51f6ca88ab9810e714bfb9b","lessThan":"e264401ce4776a288524e5b87593d4d864147115","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/crypto/intel/keembay/keembay-ocs-aes-core.c"],"versions":[{"version":"5.11","status":"affected"},{"version":"0","lessThan":"5.11","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/27ec91c29ee155cc507b2f56221fc6fab65dbb51"},{"url":"https://git.kernel.org/stable/c/5607b101d86cbee8dd1ffab784495c880ca73383"},{"url":"https://git.kernel.org/stable/c/5bbb726d27ff6dff750264e51aa665538394d0f8"},{"url":"https://git.kernel.org/stable/c/a3217fe7998622728a53dff405615e0971949eaf"},{"url":"https://git.kernel.org/stable/c/e264401ce4776a288524e5b87593d4d864147115"}],"title":"crypto: keembay - Fix AEAD unregister count in error path","x_generator":{"engine":"bippy-1.2.0"}}}}
