CVE-2026-90316

Summary

In the Linux kernel, the following vulnerability has been resolved:

drm/omap: dsi: Do not copy isr table

To be able to unregister stuff from isrs, the corresponding table was copied. Nobody seems to unregister stuff that way, so it does not help. But there are stack-allocated objects passed to these isrs giving chances of UAF of these objects if irqs are unregistered while they are handled, so better do not copy that table.
