Memory Management Issue in the Linux Kernel Graphics Driver from Intel

CVE-2025-38389

What is CVE-2025-38389?

A vulnerability in the Intel graphics driver for the Linux kernel can lead to memory management issues, specifically related to VMA (Virtual Memory Area) allocation errors. When the i915 driver is unbound after certain IGT tests, a timeline can be unintentionally held, causing issues with subsequent operations. If the allocation of a VMA fails during a ring context allocation, it may not be properly released when the driver is unbound, leading to potential resource leaks and instability. This vulnerability emphasizes the importance of proper handling of memory allocation failures within the driver, particularly in environments where signal interruptions occur frequently.
