Summary
| CVE | CVE-2026-93195 |
| State | PUBLISHED |
| Assigner | Linux |
| Source Priority | CVE Program / NVD first with legacy fallback |

| Description | In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel
The DisplayPort AUX channel gets initialized and registered during
dw_dp_bind(), but it is never unregistered, which may lead to resource
leaks and/or use-after-free.
Add the missing dw_dp_unbind() function to allow the users of the
library to handle the required cleanup, i.e. unregister the AUX adapter. |
