The crypto API's\ncompletion wrapper treats -EBUSY as a queueing status and swallows it,\npreventing the completion callback from firing. This causes callers\nusing crypto_wait_req() to block indefinitely.\n\nTranslate persistent -EBUSY to -EIO after retry exhaustion to ensure\nproper error propagation and callback invocation."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/s390/crypto/paes_s390.c","arch/s390/crypto/phmac_s390.c"],"versions":[{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"f6b263679aa72ad2e534bf93db55f2589549a40e","status":"affected","versionType":"git"},{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"e267bd142664a181474112392aeaa8b3d4b12f2e","status":"affected","versionType":"git"},{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"7a08507ea5b4d06ad8d269287913573f34467565","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/s390/crypto/paes_s390.c","arch/s390/crypto/phmac_s390.c"],"versions":[{"version":"6.16","status":"affected"},{"version":"0","lessThan":"6.16","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc3","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":"6.16","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"7.3-rc3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f6b263679aa72ad2e534bf93db55f2589549a40e"},{"url":"https://git.kernel.org/stable/c/e267bd142664a181474112392aeaa8b3d4b12f2e"},{"url":"https://git.kernel.org/stable/c/7a08507ea5b4d06ad8d269287913573f34467565"}],"title":"s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly","x_generator":{"engine":"bippy-1.2.0"}}}}
