Title
drm/fbdev-dma: Only cleanup deferred I/O if necessary
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/fbdev-dma: Only cleanup deferred I/O if necessary
Commit 5a498d4d06d6 ("drm/fbdev-dma: Only install deferred I/O if
necessary") initializes deferred I/O only if it is used.
drm_fbdev_dma_fb_destroy() however calls fb_deferred_io_cleanup()
unconditionally with struct fb_info.fbdefio == NULL. KASAN with the
out-of-tree Apple silicon display driver posts following warning from
__flush_work() of a random struct work_struct instead of the expected
NULL pointer derefs.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
