Esto presenta un problema para netfs_pgpriv2_write_to_the_cache(), que se usa para escribir folios marcados con PG_private_2 en el caché, ya que espera poder rastrear la lista folio_queue a partir de entonces para encontrar los folios relevantes, lo que lleva a un bloqueo. Solucione esto al no borrar la entrada folio_queue si vamos a hacer la copia al caché obsoleta. La limpieza se realizará en su lugar a medida que los folios se escriben en el caché. Esto se puede reproducir iniciando cachefiles, montando un sistema de archivos ceph con \"-o fsc\" y escribiendo en él."}],"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":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12","versionEndExcluding":"6.12.10","matchCriteriaId":"CAA666EC-CF76-46C6-AE86-951E128D4C0A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc1:*:*:*:*:*:*","matchCriteriaId":"62567B3C-6CEE-46D0-BC2E-B3717FBF7D13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc2:*:*:*:*:*:*","matchCriteriaId":"5A073481-106D-4B15-B4C7-FB0213B8E1D4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc3:*:*:*:*:*:*","matchCriteriaId":"DE491969-75AE-4A6B-9A58-8FC5AF98798F"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc4:*:*:*:*:*:*","matchCriteriaId":"93C0660D-7FB8-4FBA-892A-B064BA71E49E"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc5:*:*:*:*:*:*","matchCriteriaId":"034C36A6-C481-41F3-AE9A-D116E5BE6895"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:rc6:*:*:*:*:*:*","matchCriteriaId":"8AF9DC49-2085-4FFB-A7E3-73DFAFECC7F2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/38cf8e945721ffe708fa675507465da7f4f2a9f7","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/43b8d3249b0b71bad239d42dbe08ce6c938ba000","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
