Overview

Affected versions of this package are vulnerable to Out-of-bounds Read through improper handling of the loongson_gpu_fixup_dma_hang function. An attacker can cause a kernel panic or system crash by triggering access to invalid memory addresses during device initialization.

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
