Dentry of gang\ndirectory was no longer pinned, and rmdir on close was gone.\nOne problem was that failure of open kept calling simple_rmdir()\nas cleanup, which meant an unbalanced dput().  Another bug was\nin the success case - gang creation incremented link count on\nroot directory, but that was no longer undone when gang got\ndestroyed.\n\nFix consists of\n\t* reverting the commit in question\n\t* adding a counter to gang, protected by ->i_rwsem\nof gang directory inode.\n\t* having it set to 1 at creation time, dropped\nin both spufs_dir_close() and spufs_gang_close() and bumped\nin spufs_create_context(), provided that it's not 0.\n\t* using simple_recursive_removal() to take the gang\ndirectory out when counter reaches zero."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spufs: corrige la duración del directorio de pandillas. Antes de \"[POWERPC] spufs: corrige las fugas de destrucción de pandillas\", teníamos un problema con la duración de las pandillas: al crear una pandilla, se devolvía el directorio de pandillas abierto, que normalmente se elimina al cerrarse. Sin embargo, si alguien creaba un contexto perteneciente a esa pandilla y lo mantenía activo hasta que se cerraba, la eliminación fallaba y se producía una fuga. Desafortunadamente, se solucionó incorrectamente. La dentry del directorio de pandillas ya no estaba fijada y rmdir al cerrar se había eliminado. Un problema era que, al fallar la apertura, se seguía llamando a simple_rmdir() como limpieza, lo que implicaba un dput() desequilibrado. Otro error, en el caso de éxito, era que la creación de una pandilla incrementaba el número de enlaces en el directorio raíz, pero esto ya no se deshacía al destruirla. La solución consiste en: * revertir el commit en cuestión * añadir un contador a la pandilla, protegido por ->i_rwsem del inodo del directorio de pandillas. * tenerlo establecido en 1 en el momento de la creación, descartado tanto en spufs_dir_close() como en spufs_gang_close() y agregado en spufs_create_context(), siempre que no sea 0. * usar simple_recursive_removal() para sacar el directorio de pandillas cuando el contador llega a cero."}],"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":"2.6.23","versionEndExcluding":"6.1.134","matchCriteriaId":"C7D78018-09B2-438A-BDB7-F4182E5E081C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.87","matchCriteriaId":"EFF24260-49B1-4251-9477-C564CFDAD25B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.23","matchCriteriaId":"26CAB76D-F00F-43CE-BEAD-7097F8FB1D6C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.13.11","matchCriteriaId":"E7E864B0-8C00-4679-BA55-659B4C9C3AD3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.14","versionEndExcluding":"6.14.2","matchCriteriaId":"FADAE5D8-4808-442C-B218-77B2CE8780A0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:2.6.22:-:*:*:*:*:*:*","matchCriteriaId":"7F7D6C66-3384-4ACC-9D08-C5A26B4FD004"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:2.6.22:rc5:*:*:*:*:*:*","matchCriteriaId":"830B8340-2B8F-4F0A-8943-F4413411573C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:2.6.22:rc6:*:*:*:*:*:*","matchCriteriaId":"D123AAFE-3F17-45C4-9382-BA392FD022C4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:2.6.22:rc7:*:*:*:*:*:*","matchCriteriaId":"E0C256E6-2691-4478-A51C-DE580A717AB9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/029d8c711f5e5fe8cf63e8a4a1a140a06e224e45","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/324f280806aab28ef757aecc18df419676c10ef8","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/880e7b3da2e765c1f90c94c0539be039e96c7062","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/903733782f3ae28a2f7fe4dfb47c7fe3e079a528","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/c134deabf4784e155d360744d4a6a835b9de4dd4","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/fc646a6c6d14b5d581f162a7e32999f789e3a3ac","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
