Linux kernel denial of service vulnerability (CNVD-2023-56645)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A denial of service vulnerability exists in the Linux kernel, which stems from the lack of a check for the return value of kzalloc() in dpu_crtc_atomic_check in drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c. An attacker could use this vulnerability to cause a denial of service attack.
