Overview
Affected versions of this package are vulnerable to Use After Free in the zynqmp_kms process. An attacker can gain read and write access to freed kernel memory by holding an open file descriptor to the DRM primary node and issuing ioctls or mmap operations after the device has been removed, potentially leading to disclosure of sensitive information, kernel memory corruption, or system crash.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
