AI-suggested
A patch is available and should be applied to affected linux-hwe-edge kernel versions. The vendor advisory confirms the issue has been fixed. Users should update to the patched kernel versions to remediate this vulnerability.
Description
A null pointer dereference vulnerability was fixed in the Linux kernel's Rockchip DRM driver (dw_dp_remove function). The issue arises because the platform driver's remove callback may access driver data without ensuring the bind callback was executed, potentially leading to a null pointer dereference. This was addressed by removing the unnecessary call to platform_get_drvdata and referencing the device structure directly. The vulnerability affects specific versions of the linux-hwe-edge kernel and has a low severity rating. A patch is available to resolve this issue.
