In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Fix arm_smmu_device refcount leak when arm_smmu_rpm_get fails arm_smmu_rpm_get() invokes pm_runtime_get_sync(), which increases the refcount of the "smmu" even though the return value is less than 0. The reference counting issue happens in some error handling paths of arm_smmu_rpm_get() in its caller functions. ... En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iommu/arm-smmu: corrige la fuga de refcount de arm_smmu_device cuando falla arm_smmu_rpm_get arm_smmu_rpm_get() invoca pm_runtime_get_sync(), lo que aumenta el refcount de "smmu" aunque el valor de retorno sea menor que 0. • https://git.kernel.org/stable/c/3761ae0d0e549f2acdaf11f49df4ed06d256b20f https://git.kernel.org/stable/c/c4007596fbdabc29f858dc2e1990858a146b60b2 https://git.kernel.org/stable/c/fbf4daa6f4105e01fbd3868006f65c163365c1e3 https://git.kernel.org/stable/c/fe92c058199067ae90cf2a901ddf3c271893557a https://git.kernel.org/stable/c/1adf30f198c26539a62d761e45af72cde570413d • CWE-911: Improper Update of Reference Count •
