Description
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/disp: fix use-after-free in error handling of nouveau_connector_create
We can't simply free the connector after calling drm_connector_init on it.
We need to clean up the drm side first.
It might not fix all regressions from commit 2b5d1c29f6c4
("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"),
but at least it fixes a memory corruption in error handling related to
that commit.

CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a use-after-free issue in the Linux kernel's nouveau driver, specifically in the error handling of the nouveau_connector_create function. The problem occurs because the connector is freed improperly after calling drm_connector_init, leading to memory corruption during error handling.
How can this vulnerability impact me? :
The vulnerability can lead to memory corruption in the Linux kernel, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges if exploited.
