A reference count is taken at the start\nof the process in padata_do_parallel, and released at the end in\npadata_serial_worker.\n\nThis reference count is (and only is) required for padata_replace\nto function correctly.  If padata_replace is never called then\nthere is no issue.\n\nIn the function padata_reorder which serves as the core of padata,\nas soon as padata is added to queue->serial.list, and the associated\nspin lock released, that padata may be processed and the reference\ncount on pd would go away.\n\nFix this by getting the next padata before the squeue->serial lock\nis released.\n\nIn order to make this possible, simplify padata_reorder by only\ncalling it once the next padata arrives."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: padata: Arregla pd UAF de una vez por todas Hay una condición de ejecución/UAF en padata_reorder que se remonta a la confirmación inicial. Se toma un recuento de referencias al inicio del proceso en padata_do_parallel y se libera al final en padata_serial_worker. Este recuento de referencias es (y solo es) necesario para que padata_replace funcione correctamente. Si nunca se llama a padata_replace, no hay problema. En la función padata_reorder que sirve como núcleo de padata, tan pronto como padata se agrega a queue->serial.list y se libera el bloqueo de giro asociado, ese padata puede procesarse y el recuento de referencias en pd desaparecería. Arregla esto obteniendo el siguiente padata antes de que se libere el bloqueo squeue->serial. Para que esto sea posible, simplifica padata_reorder llamándolo solo una vez que llega el siguiente padata."}],"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:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-416"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.34","versionEndExcluding":"6.15.10","matchCriteriaId":"70708DCC-6F9D-4EFE-AF47-0CA615284AD2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.16","versionEndExcluding":"6.16.1","matchCriteriaId":"58182352-D7DF-4CC9-841E-03C1D852C3FB"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/71203f68c7749609d7fc8ae6ad054bdedeb24f91","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/cdf79bd2e1ecb3cc75631c73d8f4149be6019a52","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/dbe3e911a59bda6de96e7cae387ff882c2c177fa","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/f231d5d001ec75f5886c02d496a4c79edc383d45","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
