CVE-2024-46739
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.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
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.
