CVE-2024-41011

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the drm/amdkfd module in the Linux kernel, where mapping the MMIO HDP page with large pages is not allowed due to incorrect offset handling. This can expose PAGE SIZE of MMIO space on systems with page sizes greater than 4K. The GPU has an unused 4K area in the register BAR space where registers can be remapped, including HDP flush registers, to allow userspace to flush the HDP when updating VRAM.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
