AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the updated kernel versions that include the corrected page table preallocation logic to prevent out of memory conditions caused by this issue.

Description

A vulnerability in the Linux kernel's drm/imagination driver caused incorrect sizing of page table preallocation by device address. The flaw led to over-allocation of MMU pages when a mapping crossed a page table boundary, potentially exhausting system memory and causing an out of memory panic. This issue has been fixed by correcting the calculation of the page table size to avoid underflow and excessive allocation.
