However, we\ndo not hold a reference to the folio before performing these actions,\nwhich means the folio can concurrently be released and reused as another\nfolio/page/slab.\n\nGet around this altogether by just using xarray's existing machinery for\nthe folio page offsets and dirty/writeback states.\n\nThis changes behavior for tmpfs files to now always report zeroes in their\ndirty and writeback counters.  This is okay as tmpfs doesn't follow\nconventional writeback cache behavior: its pages get \"cleaned\" during\nswapout, after which they're no longer resident etc."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: cachestat: corrige read-after-free la publicación en cache walk En cachestat, accedemos a la publicación desde la matriz x de la caché de la página para calcular su desplazamiento de página y comprobar si está sucia y banderas de reescritura. Sin embargo, no mantenemos una referencia al folio antes de realizar estas acciones, lo que significa que el folio se puede liberar y reutilizar simultáneamente como otro folio/página/losa. Evite esto por completo simplemente utilizando la maquinaria existente de xarray para los desplazamientos de páginas de folio y los estados sucios/de reescritura. Esto cambia el comportamiento de los archivos tmpfs para que ahora siempre informen ceros en sus contadores sucios y de reescritura. Esto está bien ya que tmpfs no sigue el comportamiento de caché de reescritura convencional: sus páginas se \"limpian\" durante el intercambio, después del cual ya no residen, etc."}],"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:N/A:H","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.2}]},"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":"6.5","versionEndExcluding":"6.6.21","matchCriteriaId":"BC0DAF43-2BA8-4BDC-84DA-C9482F59F45B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.7.9","matchCriteriaId":"1C538467-EDA0-4A9A-82EB-2925DE9FF827"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc1:*:*:*:*:*:*","matchCriteriaId":"B9F4EA73-0894-400F-A490-3A397AB7A517"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc2:*:*:*:*:*:*","matchCriteriaId":"056BD938-0A27-4569-B391-30578B309EE3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc3:*:*:*:*:*:*","matchCriteriaId":"F02056A5-B362-4370-9FF8-6F0BD384D520"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc4:*:*:*:*:*:*","matchCriteriaId":"62075ACE-B2A0-4B16-829D-B3DA5AE5CC41"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc5:*:*:*:*:*:*","matchCriteriaId":"A780F817-2A77-4130-A9B7-5C25606314E3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.8:rc6:*:*:*:*:*:*","matchCriteriaId":"AEB9199B-AB8F-4877-8964-E2BA95B5F15C"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3a75cb05d53f4a6823a32deb078de1366954a804","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ba60fdf75e89ea762bb617be578dc47f27655117","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/fe7e008e0ce728252e4ec652cceebcc62211657c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/3a75cb05d53f4a6823a32deb078de1366954a804","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ba60fdf75e89ea762bb617be578dc47f27655117","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/fe7e008e0ce728252e4ec652cceebcc62211657c","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]}]}}]}
