Overview
Affected versions of this package are vulnerable to Improper Restriction of Operations within the Bounds of a Memory Buffer via the amdgpu_ib_commit process. An attacker can corrupt adjacent GPU-mapped memory, disclose information, modify GPU-accessible buffers, or cause denial of service by submitting a crafted command stream containing a 64-bit user fence to the VCN encoder ring through the DRM render node interface.
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
