If such an attempt fails, a local \"fail_msg\"\nstring is set and a log message output.  The job is then added to a\ncompletions list for cancellation.\n\nProcessing of any further jobs from the txq list continues, but since\n\"fail_msg\" remains set, jobs are added to the completions list regardless\nof whether a wqe was passed to the adapter.  If successfully added to\ntxcmplq, jobs are added to both lists resulting in list corruption.\n\nFix by clearing the fail_msg string after adding a job to the completions\nlist. This stops the subsequent jobs from being added to the completions\nlist unless they had an appropriate failure."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/lpfc/lpfc_sli.c"],"versions":[{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"ad4776b5eb2e58af1226847fcd3b4f6d051674dd","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"ec70d80a8642900086447ba0cdc79e3f44d42e8f","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"f05a0191b90156e539cccc189b9d87ca2a4d9305","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"b291d147d0268e93ad866f8bc820ea14497abc9b","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"16bcbfb56d759c25665f786e33ec633b9508a08f","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"c097bd5a59162156d9c2077a2f58732ffbaa9fca","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"814d3610c4ce86e8cf285b2cdac0057a42e82de5","status":"affected","versionType":"git"},{"version":"2a9bf3d011303d8da64cd5e0e7fdd95f0c143984","lessThan":"99154581b05c8fb22607afb7c3d66c1bace6aa5d","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/scsi/lpfc/lpfc_sli.c"],"versions":[{"version":"2.6.36","status":"affected"},{"version":"0","lessThan":"2.6.36","status":"unaffected","versionType":"semver"},{"version":"4.4.293","lessThanOrEqual":"4.4.*","status":"unaffected","versionType":"semver"},{"version":"4.9.291","lessThanOrEqual":"4.9.*","status":"unaffected","versionType":"semver"},{"version":"4.14.256","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.218","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.162","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.82","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.5","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.16","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":"2.6.36","versionEndExcluding":"4.4.293"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"4.9.291"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"4.14.256"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"4.19.218"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.4.162"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.10.82"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.15.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ad4776b5eb2e58af1226847fcd3b4f6d051674dd"},{"url":"https://git.kernel.org/stable/c/ec70d80a8642900086447ba0cdc79e3f44d42e8f"},{"url":"https://git.kernel.org/stable/c/f05a0191b90156e539cccc189b9d87ca2a4d9305"},{"url":"https://git.kernel.org/stable/c/b291d147d0268e93ad866f8bc820ea14497abc9b"},{"url":"https://git.kernel.org/stable/c/16bcbfb56d759c25665f786e33ec633b9508a08f"},{"url":"https://git.kernel.org/stable/c/c097bd5a59162156d9c2077a2f58732ffbaa9fca"},{"url":"https://git.kernel.org/stable/c/814d3610c4ce86e8cf285b2cdac0057a42e82de5"},{"url":"https://git.kernel.org/stable/c/99154581b05c8fb22607afb7c3d66c1bace6aa5d"}],"title":"scsi:
