kernel: fbdev: Fix invalid page access after closing deferred I/O devices
In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix invalid page access after closing deferred I/O devices When a fbdev with deferred I/O is once opened and closed, the dirty pages still remain queued in the pageref list, and eventually later those may be processed in t...

kernel: drm/i915/dpt: Make DPT object unshrinkable
In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm-boundlist. Then it tries to rewrite the PTEs via a stale CPU...
