drm/i915: 从编码器抓取intel_display以避免潜在的问题
漏洞描述信息
在Linux内核中,已修复以下漏洞:
drm/i915: 从编码器处获取intel_display以避免潜在的错误
在编码器钩子中从'encoder'获取intel_display而不是'state',以避免intel_sanitize_encoder()带来的重大问题。该函数在调用encoder .disable()和.post_disable()时将NULL作为'state'参数传递。
待办事项:找出如何实际修复intel_sanitize_encoder()的方法。

drm/i915: Grab intel_display from the encoder to avoid potential oopsies
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Grab intel_display from the encoder to avoid potential oopsies
Grab the intel_display from 'encoder' rather than 'state'
in the encoder hooks to avoid the massive footgun that is
intel_sanitize_encoder(), which passes NULL as the 'state'
argument to encoder .disable() and .post_disable().
TODO: figure out how to actually fix intel_sanitize_encoder()...
