Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm: make sure last_fence is always updated Update last_fence in the vm-bind path instead of kernel managed path. last_fence is used to wait for work to finish in vm_bind contexts but not used for kernel managed contexts. This fixes a bug where last_fence is not waited on context close leading to faults as resources are freed while in use. Patchwork: https://patchwork.freedesktop.org/patch/680080/

Executive Summary

This vulnerability in the Linux kernel's drm/msm component involves the improper updating of the last_fence variable. The last_fence is used to wait for work to finish in vm_bind contexts but was not updated correctly, leading to a situation where resources could be freed while still in use. The fix ensures that last_fence is always updated in the vm-bind path, preventing faults caused by freeing resources prematurely.

Impact Analysis

This vulnerability can cause faults in the system because resources may be freed while they are still in use. This can lead to system instability, crashes, or unexpected behavior when the drm/msm component is involved.

Mitigation Strategies

Apply the patch that updates last_fence in the vm-bind path as provided in the Linux kernel update to ensure last_fence is always updated, preventing faults due to resources being freed while still in use.
