Publication date: 2025-12-24

Last updated on: 2025-12-24

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Add check for cstate As kzalloc may fail and return NULL pointer, it should be better to check cstate in order to avoid the NULL pointer dereference in __drm_atomic_helper_crtc_reset.

Can you explain this vulnerability to me?

This vulnerability is a NULL pointer dereference in the Linux kernel's drm/msm/dpu component. Specifically, the function __drm_atomic_helper_crtc_reset did not properly check if the cstate pointer was NULL after a kzalloc memory allocation could fail. This could lead to a crash or instability when the kernel tries to dereference a NULL pointer.


How can this vulnerability impact me? :

If exploited or triggered, this vulnerability can cause the Linux kernel to crash or become unstable due to a NULL pointer dereference. This may lead to denial of service or system instability on affected devices using the drm/msm/dpu driver.
