The problem has been bisected to\n7c877586da3 (\"readahead: properly shorten readahead when falling back to\ndo_page_cache_ra()\").  The cause of the problem is that ra->size can be\nshrunk by read_pages() call and subsequently we end up calling\ndo_page_cache_ra() with negative (read huge positive) number of pages. \nLet's revert 7c877586da3 for now until we can find a proper way how the\nlogic in read_pages() and page_cache_ra_order() can coexist.  This can\nlead to reduced readahead throughput due to readahead window confusion but\nthat's better than outright hangs."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Revertir \"readahead: acortar correctamente el readahead al volver a do_page_cache_ra()\" Esto revierte el commit 7c877586da3178974a8a94577b6045a48377ff25. Anders y Philippe han informado de que los kernels recientes a veces se bloquean cuando se utilizan con NFS en el código readahead. El problema se ha dividido en 7c877586da3 (\"readahead: acortar correctamente el readahead al volver a do_page_cache_ra()\"). La causa del problema es que ra->size se puede reducir mediante la llamada read_pages() y, posteriormente, terminamos llamando a do_page_cache_ra() con un número de páginas negativo (leer positivo enorme). Revertiremos 7c877586da3 por ahora hasta que podamos encontrar una forma adecuada de que la lógica en read_pages() y page_cache_ra_order() pueda coexistir. Esto puede provocar una reducción del rendimiento de lectura anticipada debido a la confusión de la ventana de lectura anticipada, pero es mejor que los bloqueos directos."}],"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-704"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12.5","matchCriteriaId":"80D95899-614A-43BE-AD21-BA14E811ACC4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc1:*:*:*:*:*:*","matchCriteriaId":"62567B3C-6CEE-46D0-BC2E-B3717FBF7D13"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/85351e4941a253e4c50fb7048bfc19b60b4ec44b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a220d6b95b1ae12c7626283d7609f0a1438e6437","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
