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."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Se corrige la corrupción de list_add() en lpfc_drain_txq() Al analizar la lista txq en lpfc_drain_txq(), el controlador intenta pasar las solicitudes al adaptador. Si dicho intento falla, se establece una cadena \"fail_msg\" local y se genera un mensaje de registro. Luego, el trabajo se agrega a una lista de finalizaciones para su cancelación. El procesamiento de cualquier otro trabajo de la lista txq continúa, pero como \"fail_msg\" permanece establecido, los trabajos se agregan a la lista de finalizaciones independientemente de si se pasó un wqe al adaptador. Si se agrega correctamente a txcmplq, los trabajos se agregan a ambas listas, lo que da como resultado la corrupción de la lista. Se soluciona borrando la cadena fail_msg después de agregar un trabajo a la lista de finalizaciones. Esto evita que los trabajos posteriores se agreguen a la lista de finalizaciones a menos que hayan tenido una falla apropiada."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1\/AV:L\/AC:L\/PR:L\/UI:N\/S:U\/C:N\/I:N\/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"4.4.293","matchCriteriaId":"83024F84-4857-4CAF-957E-C14804BAC4AF"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.5","versionEndExcluding":"4.9.291","matchCriteriaId":"8B1EE39E-FE30-4B7D-A26F-631135BCBB3F"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.10","versionEndExcluding":"4.14.256","matchCriteriaId":"FCEB92FF-21BF-4F75-ACA1-6AE1D51A79FC"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.15","versionEndExcluding":"4.19.218","matchCriteriaId":"4F85F433-5DEA-47D3-B07E-3B1AC474D6E0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.4.162","matchCriteriaId":"51A152D8-D5CE-47BD-9041-DEE164DCE99D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.82","matchCriteriaId":"AE501832-500C-4EF1-9489-5C13674F619D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.5","matchCriteriaId":"2128A085-4C0C-4C1E-9E9C-0DD868E2170F"}]}]}],"references":[{"url":"https:\/\/git.kernel.org\/stable\/c\/16bcbfb56d759c25665f786e33ec633b9508a08f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/814d3610c4ce86e8cf285b2cdac0057a42e82de5","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/99154581b05c8fb22607afb7c3d66c1bace6aa5d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/ad4776b5eb2e58af1226847fcd3b4f6d051674dd","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/b291d147d0268e93ad866f8bc820ea14497abc9b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/c097bd5a59162156d9c2077a2f58732ffbaa9fca","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/ec70d80a8642900086447ba0cdc79e3f44d42e8f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/f05a0191b90156e539cccc189b9d87ca2a4d9305","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/16bcbfb56d759c25665f786e33ec633b9508a08f","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/814d3610c4ce86e8cf285b2cdac0057a42e82de5","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/99154581b05c8fb22607afb7c3d66c1bace6aa5d","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/ad4776b5eb2e58af1226847fcd3b4f6d051674dd","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/b291d147d0268e93ad866f8bc820ea14497abc9b","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/c097bd5a59162156d9c2077a2f58732ffbaa9fca","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/ec70d80a8642900086447ba0cdc79e3f44d42e8f","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https:\/\/git.kernel.org\/stable\/c\/f05a0191b90156e539cccc189b9d87ca2a4d9305","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]}]}}]}
