Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
iommu/msm: Unwind probe state on registration failure<br />
<br />
msm_iommu_probe() adds its devm-managed IOMMU object to<br />
qcom_iommu_devices before adding the IOMMU sysfs device and registering<br />
it with the IOMMU core.<br />
<br />
If iommu_device_sysfs_add() fails, probe returns with the object still on<br />
qcom_iommu_devices. The driver core then releases the devm allocation,<br />
leaving a dangling list entry that later list walks may dereference.<br />
<br />
If iommu_device_register() fails, the same dangling list entry remains<br />
and the sysfs device is left registered as well.<br />
<br />
Unwind the sysfs device and global list entry in reverse setup order on<br />
the corresponding failure paths.
