Overview

Affected versions of this package are vulnerable to Out-of-bounds Write through the amdgpu_cs_ioctl process. An attacker can achieve memory corruption, information disclosure, privilege escalation, and denial of service by submitting a crafted command submission with a 64-bit user fence targeting the JPEG v4.0 decode ring via 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
