Vulnerability from github – Published: 2025-12-16 18:31 – Updated: 2025-12-16 18:31

Details

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.
