CVE-2023-53534 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: mtk_drm_crtc: Add checks for devm_kcalloc As the devm_kcalloc may return NULL, the return value needs to be checked to avoid NULL poineter dereference.
A vulnerability allowing a NULL pointer dereference has been identified in the Linux kernel's Direct Rendering Manager (DRM) Mediatek component. This issue arises because the 'devm_kcalloc' function can return NULL, and the return value was not properly checked, leading to a potential dereference of a NULL pointer. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The official Linux kernel Git repository can be checked out for the latest stable releases.
