Linux Kernel i915 Product Vulnerability Due to Pointer Offset Misuse

CVE-2022-49723

Summary

The Linux kernel's i915 graphics driver was affected by a vulnerability that mismanaged pointer offsets in the error_state_read function. This issue could lead to a kernel page fault when multiple tests were executed concurrently, with one test resetting the graphics engine while the other attempted to read error state information. Such mismanagement may cause system instability and potential downtime, underscoring the importance of implementing the recent fixes to ensure proper error handling and memory management.
