When the function\nfails to grab the object `xprt`, it simply returns 0, forgetting to\ndecrease the reference count of another object `xps`, which is\nincreased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount\nleaks. Also, the function forgets to check whether `xps` is valid\nbefore using it, which may result in NULL-dereferencing issues.\n\nFix it by adding proper error handling code when either `xprt` or\n`xps` is NULL."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/sunrpc: se corrigen posibles fugas de memoria en rpc_sysfs_xprt_state_change(). El problema se produce en algunas rutas de gestión de errores. Cuando la función no logra capturar el objeto `xprt`, simplemente devuelve 0, olvidando disminuir el recuento de referencias de otro objeto `xps`, que se incrementa mediante rpc_sysfs_xprt_kobj_get_xprt_switch(), lo que provoca fugas de referencias. Además, la función olvida comprobar si `xps` es válido antes de usarlo, lo que puede provocar problemas de desreferenciación a valores NULL. Se puede solucionar añadiendo el código de gestión de errores adecuado cuando `xprt` o `xps` sean valores NULL."}],"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-401"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"5.15.63","matchCriteriaId":"185EE6AF-BD8F-4E95-80BC-9322B04CC91B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"5.19.4","matchCriteriaId":"0E669300-DA42-4ACD-86D8-68BE5F29FB88"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.0:rc1:*:*:*:*:*:*","matchCriteriaId":"E8BD11A3-8643-49B6-BADE-5029A0117325"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/76fbeb1662b1c56514325118a07fba74dc4c79fe","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/bfc48f1b0505ffcb03a6d749139b7577d6b81ae0","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/c0434f0e058648649250b8ed6078b66d773de723","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
