4).\nSince len comes from the firmware and can exceed ar->readlen, this\ncopies more data than the readbuf was allocated for.\n\nBound the memcpy to min(len - 4, ar->readlen) so that the response\nis still completed -- avoiding repeated restarts from queued garbage --\nwhile preventing an overread past the response buffer."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/ath/carl9170/rx.c"],"versions":[{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"38e240996a6a78c94ab07d461fd66e361d55c3c4","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"2d05c321d27624c413c950278d2dc8e0f44a8950","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"525036b20ef01d814a7fcd0567d123992e4479fa","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"f74e34e66379e487a09009a4f2d42470051672bd","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"500c36649f270de05a56591fcc1aaaa36687958e","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"9aee949c68dc6dccbc54333537b109c53fe2079f","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"cb7a38810cf25738176dac32dec7a146b3f959cf","status":"affected","versionType":"git"},{"version":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c","lessThan":"4cde55b2feff9504d1f993ab80e84e7ccb62791c","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/net/wireless/ath/carl9170/rx.c"],"versions":[{"version":"2.6.37","status":"affected"},{"version":"0","lessThan":"2.6.37","status":"unaffected","versionType":"semver"},{"version":"5.10.265","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.216","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.183","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.148","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.101","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.42","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.6","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"2.6.37","versionEndExcluding":"5.10.265"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"6.1.183"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.37","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/38e240996a6a78c94ab07d461fd66e361d55c3c4"},{"url":"https://git.kernel.org/stable/c/2d05c321d27624c413c950278d2dc8e0f44a8950"},{"url":"https://git.kernel.org/stable/c/525036b20ef01d814a7fcd0567d123992e4479fa"},{"url":"https://git.kernel.org/stable/c/f74e34e66379e487a09009a4f2d42470051672bd"},{"url":"https://git.kernel.org/stable/c/500c36649f270de05a56591fcc1aaaa36687958e"},{"url":"https://git.kernel.org/stable/c/9aee949c68dc6dccbc54333537b109c53fe2079f"},{"url":"https://git.kernel.org/stable/c/cb7a38810cf25738176dac32dec7a146b3f959cf"},{"url":"https://git.kernel.org/stable/c/4cde55b2feff9504d1f993ab80e84e7ccb62791c"}],"title":"wifi: carl9170: bound memcpy length in cmd callback to prevent OOB read","x_generator":{"engine":"bippy-1.2.0"}}}}
