This can be reproduced e.g. by running:\n\n    kcapi-rng -b 67 >/dev/null\n\nThere are many ways to fix this without adding back the 'break', but\nthey all seem more awkward than simply adding it back, so do just that.\n\nTested on a machine with Qualcomm Amberwing processor."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/crypto/qcom-rng.c"],"versions":[{"version":"a8e32bbb96c25b7ab29b1894dcd45e0b3b08fd9d","lessThan":"71a89789552b7faf3ef27969b9bc783fa0df3550","status":"affected","versionType":"git"},{"version":"184f7bd08ce56f003530fc19f160d54e75bf5c9d","lessThan":"8be06f62b426801dba43ddf8893952a0e62ab6ae","status":"affected","versionType":"git"},{"version":"0f9b7b8df17525e464294c916acc8194ce38446b","lessThan":"233a3cc60e7a8fe0be8cf9934ae7b67ba25a866c","status":"affected","versionType":"git"},{"version":"ab9337c7cb6f875b6286440b1adfbeeef2b2b2bd","lessThan":"8a06f25f5941c145773204f2f7abef95b4ffb8ce","status":"affected","versionType":"git"},{"version":"a680b1832ced3b5fa7c93484248fd221ea0d614b","lessThan":"05d4d17475d8d094c519bb51658bc47899c175e3","status":"affected","versionType":"git"},{"version":"a680b1832ced3b5fa7c93484248fd221ea0d614b","lessThan":"16287397ec5c08aa58db6acf7dbc55470d78087d","status":"affected","versionType":"git"},{"version":"485995cbc98a4f77cfd4f8ed4dd7ff8ab262964d","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/qcom-rng.c"],"versions":[{"version":"5.17","status":"affected"},{"version":"0","lessThan":"5.17","status":"unaffected","versionType":"semver"},{"version":"4.19.245","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.196","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.118","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.42","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.17.10","lessThanOrEqual":"5.17.*","status":"unaffected","versionType":"semver"},{"version":"5.18","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":"4.19.236","versionEndExcluding":"4.19.245"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.187","versionEndExcluding":"5.4.196"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10.108","versionEndExcluding":"5.10.118"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.31","versionEndExcluding":"5.15.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"5.17.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"5.18"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/71a89789552b7faf3ef27969b9bc783fa0df3550"},{"url":"https://git.kernel.org/stable/c/8be06f62b426801dba43ddf8893952a0e62ab6ae"},{"url":"https://git.kernel.org/stable/c/233a3cc60e7a8fe0be8cf9934ae7b67ba25a866c"},{"url":"https://git.kernel.org/stable/c/8a06f25f5941c145773204f2f7abef95b4ffb8ce"},{"url":"https://git.kernel.org/stable/c/05d4d17475d8d094c519bb51658bc47899c175e3"},{"url":"https://git.kernel.org/stable/c/16287397ec5c08aa58db6acf7dbc55470d78087d"}],"title":"crypto: qcom-rng -
