Linux Kernel Vulnerability in DRM Driver Impacting Multiple Systems

CVE-2022-50884

What is CVE-2022-50884?

A vulnerability has been identified in the Linux kernel's DRM subsystem that arises when the drm_copy_field() function attempts to copy a NULL pointer. This situation can occur if a driver fails to set required struct drm_driver fields, leading to memory access violations. Consequently, this flaw may result in unexpected crashes or system instability, presenting a security risk for affected systems running vulnerable versions of the Linux kernel.
