AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel drm/msm driver by updating last_fence correctly in the vm-bind path. Users should apply the official kernel updates or patches that include this fix. Since this is not a cloud service, remediation depends on applying the updated kernel version. Patch status is not explicitly confirmed in the provided data; users should consult the Linux kernel vendor advisory or patchwork.freedesktop.org link for the official patch and update guidance.
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/
