CVE-2024-46739
Linux Kernel NULL Pointer Dereference in UIO-HV-Generic
Description
In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix kernel NULL pointer dereference in hv_uio_rescind For primary VM Bus channels, primary_channel pointer is always NULL. This pointer is valid only for the secondary channels. Also, rescind callback is meant for primary channels only. Fix NULL pointer dereference by retrieving the device_obj from the parent for the primary channel.
