Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dp: Free resources after unregistering them The DP component's unbind operation walks through the submodules to unregister and clean things up. But if the unbind happens because the DP controller itself is being removed, all the memory for those submodules has just been freed. Change the order of these operations to avoid the many use-after-free that otherwise happens in this code path. Patchwork: https://patchwork.freedesktop.org/patch/542166/

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 in the Linux kernel's drm/msm/dp component. It occurs because the unbind operation unregisters and cleans up submodules after the DP controller is being removed, but the memory for those submodules has already been freed. This leads to use-after-free errors. The fix changes the order of operations to free resources only after unregistering them, preventing these use-after-free issues.


How can this vulnerability impact me? :

The vulnerability can cause use-after-free errors in the Linux kernel's DP component, which may lead to system instability, crashes, or potential exploitation by attackers to execute arbitrary code or cause denial of service.
