high Tenable Cloud Security Plugin ID 464138

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix slab-use-after-
 free in hdcp The HDCP code in amdgpu_dm_hdcp.c copies pointers to amdgpu_dm_connector objects without
 incrementing the kref reference counts. When using a USB-C dock, and the dock is unplugged, the
 corresponding amdgpu_dm_connector objects are freed, creating dangling pointers in the HDCP code. When the
 dock is plugged back, the dangling pointers are dereferenced, resulting in a slab-use-after-free: [
