CVE-2026-90316— drm/omap: dsi: Do not copy isr table

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： drm/omap: dsi：不要复制 ISR 表 为了能够从 ISR（中断服务例程）中注销相关项，原本会复制对应的表。但实际上似乎并没有人通过这种方式来注销内容，因此这种复制并没有带来实际帮助。然而，存在栈上分配的对象会被传入这些 ISR，如果在这些对象处理过程中中断（IRQ）被注销，就可能引发这些对象的释放后使用（UAF, Use-After-Free）问题。因此，最好不要复制该表。

Vulnerability Title
drm/omap: dsi: Do not copy isr table
Source: CVE Program / CVE List V5
Vulnerability Description
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.
