Set ctxm->type from the current loop\nvariable instead of depending on resp->type.\n\nAlso update the loop to advance type from next_valid_type in the for\nstatement, which keeps the control flow simpler for non-valid and\nunchanged entries."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/broadcom/bnxt/bnxt.c"],"versions":[{"version":"6a4d0774f02d61f8c75ffe2e38a8553410fe52e9","lessThan":"c8d53b70166d1dc463ef42adb7293e1a770822c7","status":"affected","versionType":"git"},{"version":"6a4d0774f02d61f8c75ffe2e38a8553410fe52e9","lessThan":"29732b68a6816a815d58e9ab229844c23617e1e0","status":"affected","versionType":"git"},{"version":"6a4d0774f02d61f8c75ffe2e38a8553410fe52e9","lessThan":"4ee937107d52f9e5c350e4b5e629760e328b3d9f","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/ethernet/broadcom/bnxt/bnxt.c"],"versions":[{"version":"6.8","status":"affected"},{"version":"0","lessThan":"6.8","status":"unaffected","versionType":"semver"},{"version":"6.18.22","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.12","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"6.8","versionEndExcluding":"6.18.22"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"6.19.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c8d53b70166d1dc463ef42adb7293e1a770822c7"},{"url":"https://git.kernel.org/stable/c/29732b68a6816a815d58e9ab229844c23617e1e0"},{"url":"https://git.kernel.org/stable/c/4ee937107d52f9e5c350e4b5e629760e328b3d9f"}],"title":"bnxt_en: set backing store type from query type","x_generator":{"engine":"bippy-1.2.0"}}}}
